摘　要:

近距離突出煤層群開采過程中，由於煤層之間距離較小，鄰近層的瓦斯受采動影響大量湧入開采工作麵，容易造成工作麵瓦斯超限。本文以肥田煤礦近距離突出煤層群開采為例，通過對鄰近層瓦斯湧出特征和大小進行分析與研究，從而確定合理、有效的鄰近層瓦斯湧出治理方案，保證工作麵的安全回采。

關鍵詞:

Abstract:

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.
