井下煤的自然发火是造成矿井和井下工作人员严重威胁之一。为了预防煤的自然发火,研制了一系列预防措施,其中有:采用能减少采空区漏风的开拓和开采煤层的方法,一次采全高和在采空区内尽量少丢煤;及时报废和封闭已采区和已采巷道,用泥浆灌注采区空。此外,在防治内因火灾的实践中,广泛采用检测煤的自热阶段,以便采取措施预防自然发火。在苏联煤炭工业部所属各煤矿中,在有 The spontaneous firing of underground coal is one of the most serious threats to mine and underground workers. In order to prevent spontaneous combustion of coal, a series of precautionary measures have been developed. Among them, the following measures are adopted: exploiting and exploiting coal seam that can reduce air leakage in the goaf; adopting one full height and minimizing lost coal in the goaf; Has been mining area and has been mining roadway, with mud perfusion mining area empty. In addition, in the prevention and control of internal fires, the self-heating stage of coal testing is widely adopted in order to take measures to prevent spontaneous combustion. In the coal mines belonging to the Soviet Union Ministry of Coal Industry, there are
