分析采空区松散遗煤复采过程中的自然发火特点,结合示踪气体对煤体漏风通道的检测结果,采用人工监测、束管监测等手段对巷道周围煤体的温度及气体进行监测,同时采用胶体防灭火技术和均压防灭火技术对已探测的高温区域进行治理,保证了巷道在工作面推进过程中的稳定,取得了明显的防治效果。
The characteristics of spontaneous combustion during the process of loose coal recovery from goaf are analyzed. Combined with the detection results of tracer gas on the air leakage path of coal, the temperature and gas of coal surrounding the roadway are monitored by means of manual monitoring and beam tube monitoring, At the same time using colloidal fire extinguishing technology and pressure equalization fire extinguishing technology has been detected in the high temperature areas to be managed to ensure the roadway in the face of the process of stability and achieved significant control effect.
