摘要
回采工作面瓦斯超限现象经常发生,给煤矿安全生产带来重大隐患。为了掌握回采工作面瓦斯涌出的状况及随时空的变化规律,寻找瓦斯富集地点,确保工作面安全生产。采用单元法原理对平煤新峰四矿12160工作面的瓦斯来源及构成进行了研究分析,得出了回采工作面瓦斯涌出的分布规律,为工作面防止瓦斯积聚及改变瓦斯运移通道等瓦斯治理提供必要的技术指导。
The phenomenon of gas exceeding the limit usually occurs in working face brings heavy hidden danger to the production safety in coalrnines. In order to master the situation and simultaneously changing rules of gas emission in working face, and find out the rich accumulating place to ensure the safety produetion in working face, the author adopted the unit method to analyze the origin and formation of gas in the XinFeng Fourth mine 12160 working surface in Pindingshan Coal Co. Ltd.. The distributing rule of gas emission in working face was worked out to provide necessary technological direction to the gas control issues as gas accumulating prevention and gas transporting channel alteration in working face.
