炭窑坪煤业运输大巷瓦斯治理技术研究

Research on Gas Control Technology for Transportation Roadway of Tanyaoping Coal Mine

根据炭窑坪煤业现场实践和理论分析,阐述了位于10#煤层运输大巷遇到地质变化带时的瓦斯管理及治理技术的基本方法。10#煤层运输大巷遭遇地质构造时,位于临近层的瓦斯由顶板裂隙导入工作面,造成工作面瓦斯异常的情况。该矿采取低位注浆封堵、高位打孔抽放的措施进行治理,有效保证了工作面循环作业的正常进行。

Based on the practice and theoretical analysis of Tanyaoping coal mine, the basic method of gas management and control technology is described, which is located in the coal seam of No. 10 coal seam.When the coal seam transportation roadway meets the geological structure, the adjacent layer gas is introduced into the working face through the roof crack, causing the abnormal gas at the working face.Adopted the measures to control the low level grouting, the high level drilling and drainage, which can effectively ensure the normal operation of the working surface.
