1. The safety facilities of the ground permanent gas drainage pumping station must meet the design requirements, and must be equipped with safety devices to prevent backfire, gas return and explosion. Equipment and facilities must be debugged at the end of installation, and must be accepted after debugging. 2. The pump room must have operating procedures, post responsibility system and management system for each type of work, and a card board. 3. Drainage drivers must be trained and hold relevant certificates after passing the examination. The driver of the pumping station should strictly implement the system of succession, and carefully check the safety facilities of the pumping station after succession. Observe at least/kloc-0 gas concentration, flow rate, pressure and other parameters every hour. Gas is pumped and discharged in the pipeline (gas is used in the pumping station), and recorded, and sent to the defense department, chief engineer and safety supervisor for review every day. 4. The first start of the gas drainage pump must be approved by the chief engineer, and the technical personnel of the General Prevention Department will conduct on-site command, and the gas drainage driver of the transport team will follow the operating procedures. 5. The drainage driver shall check the gas concentration near the pump body at least 3 times per shift, and the gas concentration shall not exceed 65438+/-0%. 6. The concentration of Nevas in the pipeline of the ground pumping station shall not be lower than 20%, otherwise it must be reported to the general prevention attendant immediately, and the number of tests shall be increased. The personnel on duty in the General Defense Department should promptly organize forces to find out the reasons and deal with them. 7. The closure of the drainage pump must be approved by the chief engineer. Temporary shutdown due to power failure, failure, etc. , must immediately report to the general defense department, operation department, chief engineer and safety supervision department, and take measures to deal with. Before resuming operation, it must be approved before resuming operation. 8. The discharge of circulating water of vacuum pump must be softened and recorded, and the circulating pool should be sealed.
