杨村煤矿315孤岛工作面掘进期间防灭火技术

摘要

针对杨村煤矿315孤岛工作面掘进期间存在贯通老巷、遗煤多、煤体易破碎、采空区漏风等自然发火隐患特点，制定了以喷涂堵漏、高位钻孔压注胶体为主，加强监测和及时启封、密闭为辅的孤岛面掘进防灭火技术，并在现场进行了实践应用，取得了良好的防灭火效果，保证了315孤岛工作面的安全掘进，为其他相似条件的掘进工作面防灭火工作提供了技术指导。%The 315 island driving face of Yangcun coal mine exists some spontaneous combustion hazards during the driving period, such as old roadway transfixion, much residual coal, coal easily broken, goaf air leaking and so on. Therefore, the island face fire prevention and extin-guishing technology during driving period was made, for instance, spray plugging and high borehole injecting gel based, supplemented by strengthening monitor and timely unsealed, sealed. This technology was applied in Yangcun coal mine 315 island driving face and obtained a good fire prevention effect, ensuring the safe driving and also providing technical guidance of fire control for other similar driving faces.
