摘要
赵楼矿1305工作相邻区域为开采完毕采空区,是典型高地温矿井孤岛工作面,地温高、漏风复杂使得遗煤自燃危险显著增大。为了解决启封复采期间煤自燃火灾的防治难题,采用SF6示踪技术和煤自燃束管监测技术,得到了采空区漏风规律和煤自燃危险区域。研究成果为工作面启封复采期间安全开采提供了有力的技术支撑。
The adjacent area of 1305 work face of Zhaolou mine is the mined-out goaf.It is a typical island working face in the high ground temperature mine.High ambient temperature and complicated air leakage lead to a significant increase in the risk of spontaneous combustion of residual coal in the goaf.Aimed to solve the problem of preventing and controlling coal spontaneous combustion during the unseal and compound mining of working face.The SF6 tracer and beam tube monitoring technology were used to investigate the air leakage and the coal spontaneous combustion danger area of the working face.The research results provide a strong technical support for the safe mining during opening and re-mining of working face.
