炭窑峪煤矿综采工作面瓦斯涌出规律分析及防治对策

Analysis and prevention countermeasures of the law of full-mechanized mining face gas emission at Tanyaoyu Coal

为了掌握炭窑峪煤矿综采工作面瓦斯涌出规律,针对性地采取瓦斯防治对策,实现矿井安全生产,该文通过对81801综采工作面现场实测成果分析,得出了工作面垂直煤壁方向、沿倾斜方向、采空区等瓦斯的涌出及分布规律以及工作面瓦斯涌出与推进速度、工作面配风量、周期来压的关系,从而提出了综采工作面瓦斯防治对策,对矿井今后工作面瓦斯防治有着重要的指导价值。

In order to grasp the rule of full-mechanized mining face gas emission,take some specific measures to prevent gas and realize the safety in mining produce,this paper analyze the 81801 full-mechanized mining face data in site. Accordingly,the thesis reach a conclusion,which is about the relationship between the emission and distribution regularities of vertical as well as steep directions of coal wall in mining face and coal goaf and mining face advance as well as promoting speed,air volume and periodic weighting.In conclusion,the document presents the prevention countermeasures of gas emission from full-mechanized face,which has an instructive significance of mining face gas prevention in coalmine.
