摘要
燕子山矿目前的主采煤层为易自燃煤层,巷道顶煤和采空区遗煤自然发火危险性大,严重影响矿井安全生产。为了有效防治煤炭自燃,首先对煤炭自燃特性参数进行实验室测定,掌握煤炭自燃的基本规律,在此基础上结合矿井实际条件提出了综合防灭火技术,实施效果良好,降低了巷道顶煤和采空区遗煤自然发火的危险性。
The primary mineable coal seams in Yanzishan Mine belong to spontaneous combustion seams, the major spontaneous combustion hazard of the roof coal in the roadway and the residual coal in the gob existed, which seriously impacted on the safe production of the mine. For the effective prevention and control of the coal spontaneous combustion, the characteristic parameters of coal spontaneous combustion were tested in the laboratory and the basic law of coal spontaneous combustion was thus mastered. On this basis, the comprehensive fire prevention and extinguishing technology was put forward according to the actual conditions of the mine, the satisfactory effect was achieved, and the spontaneous combustion risk of the roof coal in the roadway and the residual coal in the gob was significantly reduced.
