摘要: 针对赵固二矿14030 工作面定向长钻孔整体水力压裂区域治理条件,采取测试煤样含水率方法对压裂影响半
径进行实测考察,确定其影响范围达到上帮33 m、下帮38 m,并在掘进期间进行了验证,为矿井优化压裂施工设计、
减少钻孔工程量提供了可靠依据。

Abstract: According to the treatment condition of the whole hydraulic fracturing area with long directional drilling in 14030
working face of Zhaogu No.2 Mine, using the method of testing water content of coal sample for measurement of fracturing radius
of influence, and it was determined that the range of influence reached 33 m on the upper side and 38 m on the lower side. And
it was verified during the excavation. It provided a reliable basis for optimizing fracturing design and reducing drilling quantity.

Key words: directional drilling; hydraulic fracturing; radius of influence
