摘要
近年来,我国煤炭行业获得了快速发展,煤炭开采强度和深度不断增加,瓦斯异常部位也越来越多,煤矿瓦斯事故的发生率也有明显增加。特别是在应用采空区顶板垮落法、长壁采煤法的采煤工作面,很容易导致工作面回风隅角堆积大量瓦斯,对回采工作面的安全稳定生产有很大影响。此时高位裂隙钻孔技术应运而生,即在煤层顶板裂隙发育区设置孔位,对回采工作面的瓦斯进行治理,可有效保障工作面的安全性。因此,本文针对高位裂隙钻孔在回采工作面瓦斯治理中的应用进行了探讨分析,以供参考。
In recent years,China’s coal industry has achieved rapid development,the intensity and depth of coal mining are increasing,the abnormal parts of gas are also increasing,and the incidence of coal mine gas accidents has also increased significantly.Especially in the application of goaf roof caving method and longwall mining method,it is easy to cause a large amount of gas accumulation in the return air corner of the working face,which has a great impact on the safe and stable production of the working face.At this time,the high-level fracture drilling technology came into being,that is,to set the hole position in the seam roof fracture development area to control the gas in the working face,which can effectively guarantee the safety of the working face.Therefore,this paper discusses and analyzes the application of high-level fissure drilling in gas control of working face for reference.
