通过急倾斜煤层分段放顶煤综合防灭火技术应用的实例,对急倾斜煤层分段放顶煤开采过程中CO浓度升高的原因进行了分析,通过采取地表填埋、采空区注三相泡沫、均压通风等综合防灭火手段后,工作面一氧化碳明显下降,现场应用效果良好,并提出急倾斜煤层放顶煤回采防治自燃发火应该注意的几个关键问题。
通過急傾斜煤層分段放頂煤綜閤防滅火技術應用的實例,對急傾斜煤層分段放頂煤開採過程中CO濃度升高的原因進行瞭分析,通過採取地錶填埋、採空區註三相泡沫、均壓通風等綜閤防滅火手段後,工作麵一氧化碳明顯下降,現場應用效果良好,併提齣急傾斜煤層放頂煤迴採防治自燃髮火應該註意的幾箇關鍵問題。

Through the instance of application of synthetical technique preventing and extinguishing fire technology in section top coal caving, the reason of CO concentration increases during mining process is analyzed. Through the way of surface landfill, injecting three-phase foam and pressure balancing ventilation, the CO concentration significantly decreased. The field application effect is good and few key problems which should be pay attention to in prevention and treatment of spontaneous combustion in section top coal caving are put farward.
