东曲矿顶板走向长钻孔取代高抽巷可行性研究

Feasibility Study and Engineering Practice of Replacing High Pumping Roadway with High Level Drilling Field in Dongqu Coal Mine

针对东曲矿突出煤层工作面瓦斯含量高、瓦斯压力大、开采强度高的特点,结合当前矿井采用的高抽巷和顶板走向长钻孔抽采方法,从瓦斯抽采理论、现场实践、瓦斯抽采效果、经济性和施工周期等方面进行对比,根据工作面瓦斯分布规律,分析研究了顶板走向长钻孔代替高抽巷的可行性。

For Dongqu coal mine coal seams group face the characteristics of high gas content and big gas pressure,high mining strength,combined with extraction methods of high gas drainage way and roof to long borehole adopted in coal mine at present,based on the theoretical analysis and field practice,the gas extraction effect,economy and construction period on the contrast,feasibility analysis high pumping lane instead of high level field,finally according to the overall gas distribution regularity of working face.
