Special safety technical measures for fire prevention at the inlet

First, safety management measures

1. In order to ensure the safety of mines and prevent the occurrence of fire accidents, the mines set up a fire prevention leading group, and the office is located in the ventilation department.

2. Strengthen fire safety education for employees. Those who require access to the industrial square are not allowed to smoke. Fireworks are prohibited within 20 meters of the pits and wells.

3, wellhead signal workers, hook workers, cart workers and security personnel must be familiar with the use of fire-fighting equipment, and familiar with the storage location of fire-fighting equipment in their work area.

4. Hang a prominent “No Fireworks” warning sign outside the wellhead room. A warning sign "No fireworks in industrial squares" is hung around the industrial square.

5. The security inspection department conducts a patrol inspection, focusing on the inspection of the fire prevention facilities and preventive measures of the main well and the auxiliary well industrial square, and timely discovering and stopping violations.

6. Establish an industrial factory fire prevention measures inspection record book (table) in the mine safety production dispatching room, and the dispatching room director will review and sign it every day.

Second, safety technical measures

1. The main and auxiliary well industrial squares must be equipped with adequate fire-fighting equipment. Wellhead room must be set sand box, iron Catalpa, fire buckets, fire extinguisher inside and outside each room a group of not less than four.

2. Fire-fighting equipment must be installed in the main fan room of Fengjingkou, such as sandbox, shovel, fire bucket, fire extinguisher, fire hose, etc. The quantity must be sufficient and must not be used for other purposes.

3. The fire pool near the wellhead must always maintain no less than 200m of clean water.

4. In the vicinity of the wellhead, it is strictly forbidden to use flammable materials to set up temporary operation rooms and rest rooms.

5. No work in electric well welding, gas welding and torch welding shall be carried out in the wellhead room. If it is necessary to carry out work such as electric welding, gas welding and torch welding, safety measures must be formulated each time, and reported to Pingdingshan Yulong Energy Development Co., Ltd. for approval and filing.

6. There must be no cigarette butts or stoves for heating within 20m near the wellhead. It is not allowed to be engaged in welding, gas welding and torches.

General measures for dealing with fire

1. When the wellhead industry Guangcheng is attacked by a fire source into the wind well:

1 Immediate telephone report dispatch room;

2 quickly open the water spray screen at the door;

3 Close the fire hydrant and water bag and directly carry out the fire extinguishing source;

4 When the fire was out of control, the wellhead staff quickly evacuated from the scene.

2. Quickly organize the evacuation of the disaster area and the personnel in the threatened area, actively organize the mine rescue team to rescue the victims, and at the same time find out the scope of the fire area and the cause of the fire, and take measures to prevent the fire accident from expanding.

According to the proven fire location and scope, the downhole ventilation method is determined. When a fire occurs at the inlet wellhead, the wellbore or the windhole bottom yard, anti-wind measures should be taken. If the wind is stopped, the wind flow can be reversed. Stop the operation of the main fan. When a fire occurs in other places down the well, the direction of the wind before the accident should be maintained, and the air supply volume in the fire area should be controlled. When a fire occurs in the downhill roadway of the incoming air, it must be prevented from reversing the wind flow due to the fire pressure. Measures: When a fire occurs in the working face with biogas rushing out, normal ventilation should be maintained. If necessary, the air volume should be appropriately increased or the local area should be taken against the wind. When the roadway is investigated or directly fired, reliable and safe measures must be taken. To prevent accidents from expanding, whether it is normal ventilation or increasing or decreasing air volume, wind, wind short circuit, isolated wind flow and stopping the operation of main fans, etc. must be done:

(1) without gas accumulation, coal dust flying, causing the explosion.

(2) It does not endanger the safety of underground personnel.

(3) Do not allow the excess gas to spread to the location where the gas accumulates through fire or fire.

(4) Contribute to the organization of fire expansion, suppression of fire, and creation of conditions close to fire.

(5) In the early stage of the fire, when the fire area is not large, the manpower and material resources should be actively organized to control the fire and directly extinguish the fire. When the direct fire extinguishing is invalid, the fire prevention method should be adopted, the fire area should be closed, and the building should be closed to isolate the fire area. The location of the wall and the order of the building, when closing the fire zone, measures should be taken to prevent gas explosion.

(6) If necessary, the drainage, grouting, and sub-wind pipes should be temporarily changed to fire-fighting pipelines.

(7) At the beginning of the fire, the personnel present should be immediately organized to use water to directly extinguish the fire or use a foam dry powder fire extinguisher, sand, rock powder and other inert substances to extinguish the fire and directly report the fire source to the dispatcher, pay attention to the fire extinguishing equipment and fire. The nature must be adapted.

(8) When the fire spreads, when people are unable to access the fire, it is necessary to properly control the amount of air sent to the fire area or to short-circuit the wind to prevent the disaster from expanding when the gas is prevented from accumulating.

(9) In the wellhead room, when a fire occurs near the bottom of the well site, in order to rescue the underground personnel, the wind should be immediately applied.

(10) In the event of a fire, quickly cut off the power to the fire zone.

(11) When there is a sign of spontaneous combustion of coal seams, it is necessary to directly pay attention to the fire zone with mud.

(12) When a fire occurs in the working face, the local fan shall not be stopped and normal ventilation shall be maintained.

Disaster avoidance route

Disaster avoidance route at the fire place:

(1) Cause of the accident: Fire caused by electric running fire or other fire source.

(2) Routes for evacuation of underground personnel: In the case of anti-wind, the personnel passed through the nearest passage and reached the bottom of the auxiliary shaft and evacuated to the ground.

(3) Rescue route: It is determined according to the location of the fire source and the fire situation.

(4) Other mining facets: For any reason, fires are evacuated according to the gas disaster avoidance route.

In the coal roadway heading of each rock lane, in the event of a fire, the affected personnel quickly wear a self-rescuer, meet the fresh airflow to a safe place, and then raise the well.

Fourth, the entrance to the well well fire door

In the mine, the push-pull fire-proof iron gate is designed and installed in the main well and the auxiliary well at the appropriate time. It is usually turned on and closed in the event of a fire in the industrial square.
