近距离突出煤层群矿井邻近层瓦斯治理技术研究

Research on the gas treatment technology mining contiguous coal seam group with the outburst danger

近距离突出煤层群开采过程中,由于煤层之间距离较小,邻近层的瓦斯受采动影响大量涌入开采工作面,容易造成工作面瓦斯超限。本文以肥田煤矿近距离突出煤层群开采为例,通过对邻近层瓦斯涌出特征和大小进行分析与研究,从而确定合理、有效的邻近层瓦斯涌出治理方案,保证工作面的安全回采。

In the process of mining contiguous coal seam group with the outburst danger, because of the smaller distance between adjacent layers of coal seam, gas is inlfuenced by the inlfux of mining working face mining working face, easy to cause the gas gauge. In this paper, making the contiguous coal seam group of feitian coal ifeld as an example, analyzed and researched the emission characteristics of gas in adjacent seams, so as to determine the reasonable, effective gas emission of adjacent layers treatment plan,and ensure the safety of the coal mining face.
