摘要： 以霍州煤电集团河津杜家沟煤矿一号井为例，研究了随钻测量定向钻进技术在老空水疏放中的应用。结果表
明，采用随钻测量定向功能精确在该煤矿一号井上组煤回风上山处施工长距离定向钻孔，成孔后单孔最大涌水量达到
130 m³/h，工程疏放水量达1.065×10⁷ m³，实现了对一号井老空水的疏放和治理。

Abstract: Taking the No.1 shaft of Hejin Dujiagou Coal Mine of Huozhou Coal Electricity Group as an example, this paper
studied the application of measurement-while-drilling directional drilling technology in the drainage of goaf water. The results
showed that the measurement -while -drilling directional function was used to accurately construct long -distance directional
drilling at the upper part of the coal return wind uphill of the No. 1 shaft of the coal mine. After the hole was formed, the
maximum water inflow of a single hole reached 130 m³/h, and the engineering drainage reached 1.065×10⁷ m³. The drainage and
management of the goaf water of No.1 shaft has been realized.
