Article 2 These detailed rules shall apply to the coal mine fire prevention and extinguishing work of coal mining enterprises, coal mines and relevant units.
Article 3 The main person in charge (legal representative, actual controller) of a coal mining enterprise or coal mine is the first person responsible for fire prevention and extinguishing work in the unit, and the chief engineer is the technical person in charge of fire prevention and extinguishing work.
Coal mining enterprises and coal mines should clearly define the departments responsible for fire prevention and fire extinguishing, and establish and improve fire prevention and fire extinguishing management systems and job responsibility systems at all levels. Mines that mine coal seams that are prone to spontaneous combustion and spontaneous combustion should be equipped with professional fire prevention and extinguishing technicians who meet the needs.
Article 4 Coal mining enterprises and coal mines must ensure the investment in fire prevention and control expenses to meet the needs of coal mine fire prevention and extinguishing work.
Article 5 When mining mines prone to spontaneous combustion and self-igniting coal seams, a grouting system or an inert gas injection fire prevention system must be established, and a coal mine natural fire monitoring system must be established.

Coal mines must prepare an emergency plan for fire accidents and organize an emergency plan drill at least once a year.
Article 7 Fire prevention and extinguishing work in coal mines must adhere to the principles of prevention first, early warning, adapting measures to local conditions, and comprehensive management, and formulate fire prevention and extinguishing measures both above and below the mine.
When mining coal seams prone to spontaneous combustion and spontaneous combustion, special mine fire prevention and extinguishing designs must be prepared and comprehensive measures to prevent natural coal seam fires must be taken. According to the specific conditions of the mine, two or more fire prevention and extinguishing technical means, such as grouting, inert gas injection, and spraying of retardants, are implemented to implement active prevention, and the early warning value of fire signs is determined based on the carbon monoxide in the early stage of coal seam oxidation or the temperature of the goaf area to achieve Early monitoring and early warning and measures should be optimized and improved to meet the needs of safe mining in this working face, and comprehensively consider the post-mining goaf management, fire prevention and extinguishing needs of adjacent working faces and adjacent coal seams.
Coal mines should comprehensively analyze the results of natural fire monitoring systems, safety monitoring systems and manual inspections to achieve early detection and early disposal of underground fires.
Article 8 Coal mines shall follow the principle of coordinated disaster prevention and control, comprehensively consider the impact of multiple disaster factors, and select reasonable development layout, mine ventilation methods, coal mining methods and techniques, roadway support methods, etc.
Article 9 Coal mining enterprises and coal mines must provide fire prevention and fire extinguishing education and training to their employees, and regularly provide fire prevention and fire extinguishing professional and technical personnel with training to improve their fire prevention and extinguishing work skills and emergency response capabilities to effectively handle fires.
Article 10 When a coal mine is closed, special measures to prevent and extinguish fires in closed mines shall be formulated to prevent underground fires from occurring during and after the mine is closed.
Article 11 Encourage coal mining enterprises, coal mines and scientific research institutions to carry out technological research on coal mine fire prevention and control, develop and promote new technologies, new processes, new materials and new equipment, and improve the ability and intelligence level of coal mine fire prevention and control.
Chapter 2 General Provisions
Section 1 Internal Fire
Article 12 Internal fires are fires caused by the combustion of coal or other flammable substances due to their own oxidation and heat accumulation. The spontaneous combustion tendency of coal is divided into three categories: easy to spontaneously ignite, spontaneous combustion, and difficult to spontaneously ignite.
New mines or mines that are renovated or expanded shall report the spontaneous combustion tendency identification results of coal seams with an average thickness of 0.3m or more to the provincial coal industry management department, coal mine safety supervision department and mine safety supervision agency.
When the production mine is extended to a new level, the spontaneous combustion tendency of the exposed coal seams with an average thickness of more than 0.3m must be evaluated.
The identification of spontaneous combustion tendency of coal shall be undertaken by an institution with identification capabilities, and the undertaking unit shall be responsible for the identification results.
Article 13 All coal seams mined shall determine the shortest natural ignition period of the coal seam through statistical methods, analogies, experimental measurements, etc.
Article 14 The “three zones” of natural fire in the goaf area of the coal mining face can be divided into the dissipation zone, the oxidation zone and the suffocation zone. When mining coal seams prone to spontaneous combustion and spontaneous combustion, the distribution range of the “three zones” of natural fires in the goaf area of the coal mining face should be measured at least once for the same coal seam. When mining coal�.
Article 31 The distance between lumber yard, waste rock mountain and other storage yards shall not be less than 80m from the air inlet wellhead. The distance between the timber yard and the waste rock mountain shall not be less than 50m.
The waste rock mountain shall not be located on the windward side of the dominant wind of the air inlet shaft, on the ground with coal seams less than 10m above the surface soil layer, or within the collapse range above the air leakage goaf.
Article 32: The permanent derrick and wellhead room of a new wellhead, as well as the joint building centered on the wellhead, must be constructed of non-combustible materials.
Fire prevention measures must be formulated for the derricks and wellhead rooms built with combustible materials in existing production mines.
