摘要
系统地论述了放顶煤工作面开采过程中因瓦斯超限而实施抽放,及由于工作面持续抽放而给采空区防治自燃带来的不利因素。正确处理好防火与抽放之间的关系是防治自燃发火的前提,也是目前在放顶煤生产过程中需要解决"一通三防"工作中的首要问题,以新陆矿-440南11层二区274工作面为例进行了探讨。
This paper systematacially states that gas drainage due to gas concentration exceeding limit during top - Coal caving mining process, and the unfavorable factors had been brought to prevent the spontaneous combustion in goal because of continuous drainage at caving mining face. Correctly treat the relationship between fire prevention and drainages is the premise of preventing spontaneous combustion, which is also the primary question need to be solved in ＂One Through and Three Prevention＂ work during top - coal caving production process, and expounds by taking 274 face, No. 2 Area, South 11 th Seam, - 440 of Xinlu Coal Mine for an example.
