摘要： 根据回坡底煤矿煤层赋存条件及开采方法，在综采工作面进行了切顶卸压护巷方案的实施，并对该方案及其
实施效果进行了研究。通过S6-8 工作面不同测点的数据采集，得到超前支承压力影响范围在距离工作面73 m 以内，最
大应力值为17.8 MPa。该方案应用效果良好，具有广泛的应用前景。

Abstract: According to the occurrence condition and mining method of coal seams of Huipodi Coal Mine, the roadway protection
scheme by roof cutting pressure relief in fully mechanized mining face was implemented. This paper studied the scheme and its
implementation effect. Based on the data collection of different measuring points at the S6-8 working face, it can be obtained that
the influence range of the advance support pressure was within 73 m from the working face, and the maximum stress value was
17.8 MPa. The application effect of the scheme is good and the scheme has a wide range of application prospects.

Key words: roof cutting pressure relief; advance support pressure; fully mechanized mining face
