摘要
通过对封闭火区瓦斯爆炸危险性分析,结合同煤集团王村矿8126工作面存在瓦斯爆炸引发火灾事故的处置,认为存在爆炸危险的封闭危险性极大;分析了火区"水封"控制和从上覆层或地面灌注液态CO_2抑爆技术的优越性。
By analyzing the gas explosion risk in sealed fire area, combined with the response to the fire accident caused by gas explosion in 8126 working face of Wangcun Mine of Datong Coal Mine Group, it considered that the sealed fire area with gas exploration risk was very dangerous, the advantages of water seal control technology for fire area and explosion suppression technology with liquid state CO_2 poured from the overlying strata or ground surface were analyzed.
