(1) General measures for mine fire prevention 1. Non-combustible materials are used to support the wellbore, the bottom hole yard, the main roadway and the diverticulum. Once a fire occurs, the whole mine is threatened. Therefore, when the wellbore, the flat raft and the bottom hole yard are excavated along the coal seam, it must be built; when the rock is cut, the non-combustible material is used for support. The location where the wellbore is connected to the yard or the main road shall be built or supported by incombustible materials. The underground permanent central substation and other electromechanical chambers in the bottom hole yard must be built, and the power in the mining area is supported by non-combustible materials, from the chamber, the underground gunpowder warehouse and the roadways on both sides (need to be less than 5m) Must be built or supported by non-combustible materials. 2. Each mine must store fire-fighting materials and tools, and establish a batch of fire-fighting warehouses, and at the same time meet the following requirements; (1) The ground fire-fighting materials warehouse should be located near the wellhead room (but not in the wellhead room), and direct railway wellhead; (2) to the underground fire material library provided a production level of each transportation roadway; and (3) the type and quantity of fire fighting material library storage materials and tools, determined by the mine, and periodic inspection and replace. These materials can only be used to deal with accidents and should not be used. The materials consumed for handling accidents should be replenished in time. 3. In order to prevent the ground fire from being introduced into the underground, the fire inlet and the air inlet shall be equipped with fireproof iron gates. The iron gates shall cover the wellhead tightly and be easy to close. The entrance to the wind tunnel and the horizontal bottom hole yards are equipped with two iron doors that are easy to close or fire doors that are covered with iron on the boards. Mining coal seams with spontaneous combustion and igniting, in the mining and returning wind tunnels, must first build a firewall with a threshold, and place a door leaf near the threshold to reserve enough material to block the firewall threshold so that it can be closed at any time. 4, set fire pool and underground fire pipeline system Each mine must be set up on the ground fire pool and underground fire pipeline system. Pumps shall be installed near the fire pool, and the head and displacement shall be specified when designing the mine fire equipment. In the deep horizontal mine, in addition to the ground fire pool, the upper horizontal or production level water tank can be used as the fire pool. (2) Prevention of external fires Prevention of external fires should start with the elimination of open flames and electric sparks. The main measures are: (1) Gas mines should use safe explosives, and firearms must comply with safety regulations. (2) Correctly select, install and maintain electrical equipment to ensure that the line is intact and to prevent short circuit and overload from generating sparks. (3) It is strictly forbidden to use bulbs for heating and using electric furnaces. Underground and wellhead rooms shall not be engaged in electric welding, gas welding or torch welding. If it is necessary to carry out the above work, special safety measures must be established and reported to the mine manager for approval. And the designated person of the mine designated to be present for inspection and supervision.

Fireproof and explosion-proof safety technology is a comprehensive technology for preventing fires and explosions. It involves a variety of engineering and technical disciplines, with a wide range and complicated technology. Fire and explosion coal mine production safety of the enemy, in the event, easily causing heavy casualties and property losses of personnel. Therefore, it is necessary to implement the fire prevention work policy of “preventing prevention and supplementing with consumptionâ€, strictly controlling and managing various dangerous materials and sources of ignition, eliminating dangerous factors, and controlling fire and explosion hazards to a minimum; After the accident, the operators can quickly evacuate the danger zone and evacuate safely. At the same time, the fire should be extinguished in a timely and effective manner to prevent the spread and disaster.
