摘要
针对白石崖煤矿巷帮及顶煤自燃,采用注水泥浆加固火区周边煤帮、火区注高分子灭火胶体和注胶后巷道表面喷浆的手段,安全、彻底地处理了自燃火区。高分子胶体扑灭煤层火灾时,应对火区附近巷道进行加固,防止顶板事故;灭火后宜对发火巷道表面进行喷浆处理,防止胶体材料因蠕变而缓慢漏出。
According to the coal spontaneous combustion of both sides and roof of roadways in Baishiya coal mine,by taking the measures of reinforcing sidewalls by cement slurry grouting,injecting polymer gel and roadway shotcreting,the fire zone was treated completely. When using the polymer gel for fire extinguishing,to prevent roof accidents,the roadway near the fire zone must be reinforced. To prevent the slow leakage of colloidal materials,the roadway surface must be treated by shotcreting after fire extinguishing.
