龙口矿区易自燃煤层综合治理技术

Comprehensive control technology of spontaneous combustion seam in Longkou Mining Area

针对三软地层易自燃煤层在煤巷掘进、工作面回采、工作面撤面过程中及工作面撤出后的采空区中等的漏风裂隙发育、漏风通道繁杂、漏风途径隐蔽、防火难度大、火灾事故频发等状况,进行了研究和探索,并在总结以往火灾事故教训的基础上,采取了具有针对性的综合治理对策,从根本上遏制了往年火灾事故多发、经济损失惨重、负面影响大的势头,取得了连续数年消灭高温火点和一氧化碳超限的显著成效。

According to spontaneous combustion seam easy occurred in the three soft strata ( soft roof, seam and floor), the paper researched and discovered the air leakage fissure development, complicated air leakage channel, hidden air leakage accesses, difficult fire control and fire accidents frequently occurred in the seam gateway driving, coal mining face operation, coal mining face removing operation and goaf after the coal mining face removed. Based on the summarization of the lessons from the previous mine fi...
