摘　　要：基于定向钻进原理,探讨了深孔定向钻进技术的优缺点,并结合冀中能源东庞矿的实际条件,分析了深孔钻进技术在煤层瓦斯抽采中应用的可行性。通过对高位定向长钻孔在抽采过程中的瓦斯浓度及流量进行观测分析,确定了利用定向钻孔进行高位瓦斯抽采方法的有效性,从而为深孔定向钻进技术在瓦斯治理方面的推广应用提供了一定的技术支持。Based on the theory of directional drilling, analyzes the advantages and disadvantages of deep borehole directional drilling technology. According to the actual field condition in Dongpang coal mine of Jizhong energy resources co., ltd., the feasibility that the deep borehole drilling technology applied to extracting coal seam gas in this mine is discussed. The effectiveness of high-position gas extraction method was confirmed by observing and analyzing the gas concentration and flow in the high-position directional deep borehole, which provide the deep borehole directional drilling technology a technical support for a wider application in the area of gas control.
