摘要
通过对常村煤矿综放工作面的瓦斯涌出规律的研究,分析出大气压力变化对义马矿区的影响。在地面大气压力较小的4月至8月,重点做好采煤工作面的瓦斯防治工作,这段时间要加强关注采煤工作面上隅角及回风巷的瓦斯涌出量,采用防治瓦斯的有效措施,提高瓦斯抽采效率,通过上隅角回风的合理布局,有效地防治瓦斯异常涌出。在地面大气压力较高的11月至次年1月,适当停止瓦斯抽放泵的运行,则可以节能降耗,降低成本。
Through the study of the gas emission law in fully mechanized coal face of,Changcun Coal Mine,analysis of the impact of changes in atmospheric pressure to Yima area. In the ground atmospheric pressure smaller from April to August,focus on doing the gas emission quantity of the upper corner and return airway of fully mechanized coal mining face. Taking effective measures to control gas,and improve the gas extraction efficiency,through the reasonable layout,effectively control gas emission abnormality. In the ground atmospheric pressure higher from November to January the following year,appropriate to stop gas drainage pump operation,can save energy,and reduce consumption and costs.
