(1) Passengers should queue up to get on and off. Crowding or slapstick is not allowed. Always pay attention to the front roof. It is forbidden to expose body parts outside the car.

(2) Passengers should sit in the car, no standing or playing, and always pay attention to the front roof; It is forbidden to expose body parts outside the car.

(3) The driver of explosion-proof car should stop slowly and start slowly, and it is forbidden to slam on the car. Before driving, he should signal to remind passengers to pay attention to safety.

(4) The driver of explosion-proof vehicle should carry portable instruments with him. When the gas concentration reaches 0.7%, it is forbidden to start the vehicle.

(5) The driver of explosion-proof vehicle should always pay attention to the floating personnel in front. He must honk his horn when he finds a pedestrian in front. If a pedestrian has no avoidance consciousness, he must stop at a distance of 50 meters and honk his horn. Only after the pedestrian hides in a safe place can he continue driving. Stop 20 meters in advance, and wait for people to hide in a safe place before passing.

(6) Drivers and passengers should see clearly the road top ahead, especially when going up and down slopes, and should slow down. When driving fast, they should signal in advance. Because the underground conditions are not good, they have to drive slowly at a constant speed.

(7) The driver should pay attention, and don't talk nonsense, which will affect driving; When driving, the speed should be even, and it is forbidden to hit the roadway, water pipes, drainage pipes and cables.

(8) When shifting gears, the operation method of two-time clutch is adopted. It is forbidden to break gears or shift gears automatically without stepping on the clutch, causing accidents.

(9) Try to avoid parking on the ramp. Unless there is an emergency, when you need to stop, you should step on the brake pads and tighten the brakes at the same time, so that the engine can be turned off and put into reverse gear. The driver must not leave the driving position to prevent the brake from loosening and causing a landslide accident.

(10) It is forbidden for passengers to be overcrowded, and it is forbidden to pick up or jump in the middle.

(1 1) It is forbidden to get on or off the bus until it stops.

(7) When the protection device gives an alarm, it must stop and troubleshoot within 1min, and it is forbidden to work in spite of illness.

(3) Measures to prevent gas accidents

1. The gas concentration in the return air flow of the mining face reaches 0.7%, so it is necessary to stop working, find out the reason and deal with it. When the gas concentration in the return airflow of the coal mining face reaches 65438 0%, the monitor must inform the driver to withdraw from the maintenance workshop. When the gas concentration in the airflow within 20m near the explosion-proof vehicle reaches 65438 0%, it is necessary to cut off the power supply, evacuate people and formulate measures for treatment.

2. When the power supply is cut off because the gas concentration exceeds the specified value, the explosion-proof vehicle can only be started when the gas concentration drops below 0.7%.

3. When shooting is needed, strictly implement it? One shot and three inspections? Three-person interlocking programmed shooting system, if the driver is in the maintenance workshop of the wind lane, the monitor must call the driver before shooting, and the driver must evacuate to the air door. After firing the gun for 30 minutes, he can enter the maintenance workshop and call to ask about the situation. Only under special circumstances can he do his homework, otherwise, he will immediately evacuate to the track.

4. Reasonable air supply, strengthen the management of gas accumulation points (such as goaf, upper corner of return air in coal mining face and roof caving hole, etc.). ), and increase the air volume at the gas accumulation point or adjust the air volume with air guide facilities.

5. Improve the gas monitoring device in coal mining face. The gas probe in the wind tunnel is not more than 10m away from the coal mining face. Foreman on duty, shearer driver, pumping station driver and electrician must carry portable instruments with them. The monitor carries portable instruments and hangs on the upper corner of the tail.

6. The workers in the wind lane maintenance workshop carefully protect the monitoring device and observe the concentration of the Chabas probe in each shift. Once the gas concentration is found to be above 0.6%, they must call the mining face and the personnel on duty and take immediate measures to deal with it. When the gas concentration is not less than 0.6%, it is forbidden to drive an explosion-proof car.

7. Arrange 1 full-time gas inspector per shift. Gas inspectors often check the changes of coal seam structure and gas content in return air at coal mining face. When there is an early warning of gas outburst, work should be stopped immediately and personnel should be evacuated.
