类比分析法在防灭火工程中的实践与应用
Practice and Application of Analogy Analysis Method in Fire-Fighting Engineering
摘要:
针对后安煤矿90303工作面上隅角出现CO气体的实际情况，采取类比分析法分别对90303采空区遗留煤炭自燃情况、邻近的90302采空区以及902采区CO情况、强矿压作用下从大空间采场覆岩结构上分析4#煤层采空区CO对90303工作面影响情况进行了逐一分析。分析原因后并采取了针对性的治理对策收到了良好的治理效果，保证了矿井的安全生产。
Abstract:
Aiming at the actual situation of CO gas in the upper corner of 90303 working face in Houan Coal Mine, and according to the actual situation, analogy analysis was adopted to analyze the sponta-neous combustion of coal remaining in the 90303 goaf, the adjacent 90302 goaf and the CO in the 902 mining area. Under the action of strong mine pressure, analyze the influence of CO on the 90303 working face in the 4# coal seam goaf from the overburden structure of the large space stope. After analyzing the reasons and adopting targeted treatment countermeasures, good treatment results have been received and the safe production of the mine is guaranteed.
