针对杉木树煤矿S3012工作面自然发火期短,地质构造复杂,大小断层及其牵引构造较多,过断层期间极易产生煤层自燃隐患的实际情况,为保证该工作面安全回采,通过对自燃隐患因素分析,建立自然发火预警体系,采取减少采空区漏风、加强采空区抽放管理、两巷煤体固化与封填堵漏、注浆注氮等综合防灭火技术措施,有效抑制了过断层期间煤层自燃。
In view of the fact that there is a short spontaneous firing period, complex geological structure, large and small faults and their traction structures in S3012 face of Fushulu Coal Mine, it is very easy to produce the actual situation of potential spontaneous combustion of coal seam during the fault period. In order to ensure the safe recovery of the working face, Factor analysis, the establishment of a natural fire early warning system, to take to reduce the gob of air leakage, to strengthen the gob area drainage management, two lane coal solidification and sealing plugging, grouting injection of nitrogen and other comprehensive fire prevention and control measures to effectively suppress Coal spontaneous combustion during faults.
