【摘要】：白芨沟煤矿010202区段工作面在开采过程中受到地表渣台高温火区和本煤层及邻近上覆采空区浮煤自然发火威胁,且地面裂隙发达进而导致采空区漏风严重,极易加剧煤炭自燃进而引起火灾耦合事故。因此,根据采空区火源探测技术及束管监测为采空区防灭火提供理论指导,为提高上覆采空区防灭火效果引进复合浆液防灭火理论,即在传统采空区注浆灭火的基础上加入相关添加剂来提高浆液的黏性、流动性和保湿性,在实验的基础上找出具有最佳防灭火效果的复合浆液,最后根据采空区束管监测的温度及有害气体浓度验证具备最佳浓度和黏性的复合浆液的实践效果,进而提出010202区段工作面合理的防灭火措施计划,保证工作面安全生产。
[Abstract]:In the mining process of Section 010202 of Baijigou Coal Mine, the coal face of section 010202 is threatened by the spontaneous combustion of floating coal in the high temperature area of the surface slag platform and the coal seam and its adjacent overlying goaf, and the development of the surface cracks leads to serious air leakage in the goaf. It is easy to aggravate coal spontaneous combustion and cause fire coupling accident. Therefore, according to the detection technology of goaf fire source and the monitoring of beam tube, the theory of compound slurry fire prevention and extinguishing is introduced in order to improve the effect of fire prevention and extinguishing in goaf, and to provide theoretical guidance for the prevention and fire extinguishing of goaf. On the basis of traditional grouting fire extinguishing in goaf, adding related additives to improve the viscosity, fluidity and moisture retention of the slurry, on the basis of the experiment to find out the best fire prevention and extinguishing compound slurry, Finally, according to the practical effect of the compound slurry with the best concentration and viscosity verified by the monitoring temperature and the concentration of harmful gas in the goaf, the reasonable fire prevention and extinguishing measures plan of the 010202 section working face is put forward to ensure the safety of the working face.
