摘要
为治理新巨龙公司煤矿8301高地温特厚煤层工作面末采期间受冲击地压事件影响,造成该综放面因长时间停采致使出现煤自然发火的问题,创新性地提出了构建高地温特厚煤层综放面末采-撤架期间的双重防灭火体系,即“三步法撤面技术体系、一张图撤面管理体系”,对采空区遗煤自燃危险区域实现超前预防、治理和监测监控。同时通过气体浓度变化来验证工作面采空区超前预防、治理的效果,并指导下一步防灭火工作的重点采空区危险区域。
In order to solve the problem of spontaneous combustion of coal in goaf of 8301 high ground temperature and extra thick coal seam in Xinjulong coal mine due to the impact of rock burst during the final mining period.Innovatively puts forward the construction of double fire prevention and extinguishing system during the period of final mining and support removal of fully mechanized top coa caving face in high temperature and extra thick coal seam,namely "three-step technology system and one map removal management system",so as to realize advanced prevention,treatment and monitoring and monitoring of the goaf coal spontaneous combustion risk area.At the same time,using the means o monitoring gas,through the change of gas concentration to verify the effect of advance prevention and treatment of goaf,and guide the key areas of next step fire prevention and extinguishing work in the dangerous area of working face goaf.
