Model essay on coal mine investigation report 1
According to the report of the Party, education is the cornerstone of national rejuvenation, and educational equity is the important foundation of social equity. Optimize the educational structure and promote the balanced development of compulsory education. Renew educational concepts, deepen teaching contents and methods, reduce the academic burden of primary and secondary school students, and improve students' comprehensive quality. Strengthen the construction of teachers, and strive to improve the quality of rural teachers. "
It can be seen that education plays an unshakable and important role in China's modernization drive, and our party and government also attach great importance to it. Primary school is the golden age to cultivate good habits, thinking ability and innovation ability. Therefore, laying a good foundation for primary education will play a great role in the study of secondary schools and universities in the future. The educational conditions and teaching level in rural areas are generally lower than those in urban primary schools. Therefore, rural compulsory education, especially primary education, is very important. Judging from the situation in recent years, the government has paid more and more attention to compulsory education, and the overall appearance of rural primary schools has also undergone tremendous changes. First of all, in the teaching hardware facilities, the dilapidated tables and chairs have been replaced by new tables and chairs, and books, cultural and sports equipment and various teaching instruments are also equipped accordingly. Secondly, the number of teachers in the school has increased. However, I think there are still many disadvantages in rural primary education, mainly in the following aspects:
First, the school is small in scale and its hardware facilities are backward.
Although rural primary schools have made great improvements in school buildings and hardware facilities, there is still a big gap compared with urban primary schools. I have been to some coastal areas, and compared with other places, we are really backward. As leaders of rural primary schools, we think about where to get school funds every day, while other leaders think about where to spend school funds every day. What a different world! Due to the limited funds for rural education, many needs cannot be met. Most rural primary schools lack or incomplete computer rooms and multimedia classrooms. The number of books in the library is small and outdated, and the sports equipment is poor. A lot of equipment is just for decoration, and it is often short of funds, so it is impossible to buy new ones.
Second, the professional level of teachers is not high and the workload is heavy.
1, teachers have a heavy burden. There are many older teachers in our rural primary school. These teachers have rich teaching experience, but their teaching methods are backward, and there are great problems in teaching quality. Because rural information is relatively closed and there is little communication with the outside world, primary school teachers' educational concept lags behind and their educational and teaching ability is not strong. Most teachers still use the traditional method of "a piece of chalk+a mouth+a book" to complete their own teaching, while students' "learning method" is still the five-stage method of "listening, writing, reading, reciting and testing". This primitive and backward teaching method not only can not meet the needs of contemporary teaching, but also increases the burden on teachers and students, consumes a lot of time and energy, and achieves twice the result with half the effort. At the same time, rural parents are forced to go out to work because of life, which makes the absence of family education in rural areas serious. Putting all the educational responsibilities that should be borne by families and parents on teachers and schools requires teachers to give more care and care to these students in their study and life, which undoubtedly increases the burden on teachers.
2. Teachers' ideas are backward. Some old teachers are seriously influenced by the inherent traditional teaching concept and are used to using the traditional teaching mode. They are old-fashioned, backward in ideas, weak in reform and innovation, afraid of difficulties, and lack the initiative and enthusiasm to practice curriculum innovation. It is natural to follow the old road of traditional teaching in teaching, which affects the improvement of education quality.
3. Teacher training is backward. The urgent task is to do a good job in teacher training and improve teachers' quality. The renewal of teachers' ideas and the mastery of teaching materials and curriculum standards depend more on teachers' training. However, at present, there is a general phenomenon that sending training and school-based training are not in place in rural schools.
Three reports of coal mine investigation, various reports, many school teachers going out will affect the teaching in the school. Secondly, there is a shortage of funds for running schools and training. School-based training is not in place, mainly because the number of subject teachers in the school is insufficient, and it is difficult to form an atmosphere and ensure the quality of professional training and teaching research.
4. Teachers are backward in self-study and research. The new curriculum emphasizes the openness, intersection, integration and comprehensiveness of subject teaching content. Teachers' traditional professional knowledge reserves can no longer meet the needs of implementing new curriculum teaching. Teachers must strengthen self-study and research, constantly "recharge", constantly enrich and improve their knowledge structure, and regard strengthening self-study and research as the need of career development. However, due to geographical, economic and hardware constraints, rural schools have extremely limited resources for teachers to acquire knowledge and information. Many schools have no internet and lack books. Limited books can't be updated in time, and most of them are out of date. Teachers suffer from lack of information to learn, and self-study suffers from lack of information to consult. Collecting information, perfecting knowledge structure and improving teaching strategies are affected, and new situations and problems encountered in teaching are solved without auxiliary information. In addition, due to the limitation of school learning resources, the achievements of teachers' off-campus training can not be consolidated, digested and understood in time, and can not be internalized and deepened. Over time, the training results are lost. The backwardness of teachers' self-study and research has seriously affected their professional development and quality improvement.
Third, quality education is difficult to implement and curriculum reform is difficult.
Rural education has been shrouded in the shadow of exam-oriented education. Under the restriction and influence of the big environment, teachers take students' high scores as an important goal, and schools also take students' achievements as the only basis to measure teachers' teaching level. Although music, physical education, artistic English and other courses are offered, it is difficult to guarantee that students can't develop physically and mentally in an all-round way, and their knowledge is narrow and their concepts are backward.
The new curriculum specialty is far ahead. Especially after the new curriculum reform, rural teachers who are used to using the traditional teaching mode feel confused and afraid of difficulties in the organization and implementation of the new curriculum. Therefore, it is necessary to strengthen the professional guidance for teachers and give full play to the leading role and radiation role of backbone teachers. Rural schools generally feel that there are too few "sensible" people in the implementation of the new curriculum and their strength is insufficient. Although some teachers have participated in a certain degree of training, due to the influence of their own quality and group environment, the conversion rate of the new curriculum is not high, so it is difficult to turn training income into teaching practice and become the backbone and leader of the school to implement the new curriculum. In addition, due to the regional characteristics, the school curriculum reform lacks regular and effective guidance from the superior business departments. The lack of guidance on the implementation of curriculum reform has restricted the smooth progress of the new curriculum reform in rural schools.
Fourth, there are fewer primary schools at village level, which makes it inconvenient for students to go to school.
Due to poor teaching conditions, backward teaching equipment and other factors, more and more parents go out to work, send their children to urban schools with better teaching quality, and family planning work is also in place, so the number of students is decreasing year by year, and many schools are merged into one. To a certain extent, the merger of villages and schools is conducive to concentrating educational resources and saving educational expenses. In fact, merging schools is not an easy task. It involves students' long journey to school, which hurts the feelings of some villagers and so on. At that time, the merged schools also encountered many difficulties. Later, the government gave each student who went to school for more than 5 kilometers 150 yuan, and the school was merged successfully. However, at present, rural primary schools do not provide accommodation, which brings inconvenience to some students who live far away. Pupils are young, running back and forth every day is not only a waste of time, but also difficult to ensure the personal safety of students. But to live on campus, the school has no dormitory.
The gap between urban and rural areas is widening.
Rural primary schools can't compare with urban primary schools in teaching level, and the gap is getting bigger and bigger, which can be attributed to five reasons:
1, the crude hardware, that is, teaching equipment, can not create good learning conditions for students;
2. In terms of software, teachers are weak, rural conditions are poor, most young graduates are unwilling to teach in rural areas, the average age of teachers is relatively old, the knowledge structure is relatively old, and the work lacks the passion and vitality of young people.
3. Parents' quality is low, and their awareness of urging their children to learn is weak. Some people even send their children to school and let them stay in school to avoid him running around or running around.
4. Children are naturally fond of playing, and will not spontaneously have interest in learning without proper external pressure.
At present, the social employment situation is not optimistic, and it is common that college graduates can't find jobs. At this time, many migrant workers of the same age have been able to basically maintain their own lives, and many farmers will think that "reading is useless" and "one more college student will have one more poor household". With this understanding and environment, students' enthusiasm for learning will gradually weaken.
To sum up, due to the unbalanced economic development in all parts of the country, the development of rural education is difficult and not optimistic. Rural primary education accounts for half of compulsory education, so we must attach great importance to its disadvantages. If basic education is not solid, developing education can only become an empty slogan. The solution of its problems is also the only way to achieve educational fairness and balance. Otherwise, it is equivalent to losing most of the primary school stage and the foundation of the whole basic education, and there is no quality education for all. Therefore, rural education must keep up with the pace of social development and should not be forgotten by society. "No matter how poor you are, you can't be poor in education, and you can't suffer from children." How hard it is to really do it! Only by taking measures to completely change the current situation of rural children receiving the worst school education and strengthening the weak links in the basic education chain can rural primary schools get out of the predicament, lay a solid foundation for the development of rural basic education and promote the development of rural education.
Comrades have two famous sayings: "Leaders who ignore education are immature leaders who lack foresight, so they cannot lead the modernization drive. Leaders at all levels should pay attention to education as much as economic work. " . We must do everything possible to be patient in other areas, even at the expense of a little speed, to solve the education problem well. Basic education is a future-oriented cause, and today's students are the backbone of future modernization. Do a good job in compulsory education, especially in rural areas.
Model essay on coal mine investigation report II
According to the requirements of the group company and the unified deployment and arrangement of the Party Committee of our mine, and according to our team's activity plan of striving for Excellence, the whole team took active actions, carefully designed the theme activities and theme objectives of striving for Excellence, actively went deep into the team, conducted research and solicited opinions in the work.
During the research activities, on the one hand, I learned that the broad masses of workers sincerely support the activity of "striving for Excellence", and they are also trying to master and practice it in depth, thus promoting the sound and rapid development of our team's work. However, in the process of investigation, we need to take more active and effective measures to solve the problems existing in the project quality, so as to lead the activity of striving for Excellence to a deeper level.
First, it is not because I dare not do difficult things, but because I dare not do them.
With the advance of 6 1 drilling footage, the distance from the center line of the hole is getting farther and farther, which makes it more and more difficult for workers to construct and has higher requirements for mastering the size. The existing solution is to move the center line forward to correct the direction of the road. But every time the center line moves forward, it will bring big and small errors, and it will also affect the quality of underground engineering over time.
In the dark underground, you can't see the position of the center line, just like losing the direction of progress. How to ensure the engineering quality? Is there a way to kill two birds with one stone? Can the center line be moved forward without affecting the normal use of workers? How can we bring convenience to employees, reduce difficulty, reduce time waste and improve work efficiency?
With many questions and technical problems, from the middle of last month, the team leader organized a special working group to go deep into the underground 6 1 second epithelium and 6 1 16 gas roadway for many times to investigate, listen carefully to the difficulties encountered by workers in their work, and according to the complex geological structure and harsh production and operation environment, stretch out the ruler by themselves, measure the center line size and roadway distance repeatedly, and fill in the data carefully.
"Hard work pays off" in the face of various technical problems, after numerous attempts, failures and sweat, finally overcame various difficulties and successfully extended the center line, which will not affect the normal use of workers and will not produce errors in the process of moving the center line. On the basis of "two points determine a straight line", it is added to "three points", "four points" and "five points" ... With the continuous extension of the production front, there are more and more "key points" on the center line. By determining several points on the center line, the direction of the center line is determined, thus extending the center line and pointing out the direction for underground workers.
Second, through this survey, several problems existing in our team are reflected.
1. In the process of safe production, it is not difficult to see that our team still lacks technical talents and the knowledge level of existing workers is low.
2. The number of college students in our team accounts for 10% of the total number of our team. How to make good use of and cultivate the existing talents is the primary task of our team in the future.
3. The ability of the staff in the team to solve problems is limited, and the psychology of being content with the status quo is widespread.
4. Employees are too conservative to break the tradition, lacking leadership and the spirit of being the first.
Three, in view of the above problems, formulate corresponding measures and solutions.
1. Strengthen the combination of workers' theory and practice. Strengthen case teaching, pay attention to comprehensive training of professional ethics, safety legal awareness and practical safety construction skills: fully consider the fact that employees' educational level is not high, strengthen skill training, and make the training content easy to understand and master.
2, the team should hold some "job skills practice" activities, according to the special situation of each job site, the safety measures of each process, the safety operation procedures of each equipment. In a workplace, a certain piece of equipment is used to safely complete a certain process, and everyone goes on stage to operate, master the safety operation procedures of all equipment, strictly abide by various rules and regulations, and earnestly implement safety measures. Operators should be trained in safety regulations, safety awareness, safety operation skills, accident prevention and treatment, disaster avoidance and self-help. Only with rich knowledge and good work experience can we have the ability to solve problems.
Through this investigation and study, we still encountered some difficulties in production. How to find problems in difficulties and whether we can find solutions in problems requires the whole team to unite as one and strive to build a bigger and stronger second team.

Iv. Situation during the construction of the first phase of China Coal Fifth Construction Project:
The construction team entered the site in August, 20__, and tried to dig in February, 65438+ 16, and entered the site four months earlier.
1, auxiliary shaft design: net diameter 10.4m, depth 702m 150m, with double-layer shaft lining at the upper part and single-layer shaft lining at the lower part. -150~-524m with a wall thickness of 900mm, 700mm below -524m with a concrete grade of C45~C65…… and a freezing depth of 524m. The freezing section adopts the pre-grouting construction method of the working face, with 125m as a grouting section, grouting 125m, and construction 100m.
2. Construction equipment: super-large sinking derrick is adopted, with a bottom span of 2 1×2 1m and a height of 29.2m, and a two-story crown block platform; Hanging plate adopts double-layer hanging plate, which is suspended by ∮42mm steel wire rope; Two sets of HZ-6 central rotary rock grab, 0.6m? Grab bucket; 16 arm double umbrella drill, single 6 arm, 4.5m long drill pipe, ∮50mm alloy steel drill bit; 5m？ Bucket; MJ-4.0- 10 integral steel formwork; Three sets of lifting equipment, one set for 2JK-4/ 15 hoist and two sets for JK-2.8/ 15.5 hoist; 3m for concrete? Bottom tipping bucket; The horizontal pump is used for pumping water. The horizontal pump is installed on the hanging plate, and a water tank is installed on the hanging plate. The water at the bottom of the well is pumped into the water tank of the hanging plate by an air pump or an electric pump.
The main shaft adopts three sets of lifting equipment, and the air shaft adopts two sets of lifting equipment.
3. Construction technology: drilling and blasting, with a depth of 4.5m The whole well is charged at one time and detonated at the same time, and the amount of explosives per gun is 850~900kg. The central rotary rock loader loads rocks and the bucket is lifted. After the large formwork is fixed, the concrete is discharged to the ash tray on the hanging plate through the bottom hopper, and poured into the formwork through the wear-resistant hose to build the shaft wall. During the construction of single-layer shaft wall, the shaft wall grafting grouting is carried out on the hanging plate. This construction method is a scientific research project in cooperation with China University of Mining and Technology, and the specific effect has not been tested.
4. Construction progress: the maximum footage 1 100 m in the frozen section can be guaranteed normally.
5, problems encountered in the construction:
(1), water consumption: when the auxiliary shaft is constructed to Matoumen, the maximum water consumption is more than 800 m? /h, the spindle reaches 1000m? /H. Now the wellbore water consumption is 7m? /h or so, spindle 30m? /h or so, the wind well is 36m? /h or so
(2) The shaft is frozen at full depth, and the driving speed is fast, but there are many hidden dangers, mainly because the frozen hole can't be blocked by itself in the rock, which causes the frozen hole to conduct water.
(3) There is an aquifer above coal 2 10m, and there is an aquifer above coal 3 20m, which should be paid attention to during construction.
6. Preparation for the construction team to enter the site: Before entering the site, the mine substation was built according to permanent design, but the installed equipment was temporary; The boiler room is built by the construction unit as a temporary boiler; The water source shall be prepared by the construction unit, and temporary water supply pipelines shall be laid.
7. Regarding the bidding: the mine bidding adopts the binding bidding of freezing construction, with one bid section for the main air shaft and one bid section for the auxiliary shaft. China Coal Company won the bid for mine construction, and the freezing construction units are all units of China Coal Company.
8. About the effect of freezing the single-layer shaft wall: because it is not completely thawed, there is no experimental result for the actual effect. In order to confirm the effect, forced thawing and perforation grouting are carried out in the air shaft.
