2637巷掘进过交叉空巷技术研究与应用

Research and Application of the 2637 Roadway Driving Through Cross Empty Roadway

云冈矿2637巷掘进期间需通过下方同层两条空巷的交叉点,为保证2637巷顺利通过空巷上方,结合2637巷地质条件及交叉巷位置情况,设计了过交叉空巷方案及支护方案。对空巷进行粉煤灰充填、空巷影响区补打锚索锁口钢梁配合井字型木垛等措施,平稳通过交叉空巷。

During the excavation of the 2637 roadway in Yungang Coal Mine,it is necessary to pass through the intersection of two empty roadways in the same layer below.In order to ensure the smooth passage of the 2637 roadway above the empty roadway,combined with the geological conditions of the 2637 roadway and the location of the crossing roadway,the scheme and support scheme of crossing empty roadway are designed.Measures such as fly ash filling in the empty roadway,filling anchor cable and locking steel beam with well-shaped wood stack in the affected area of the empty roadway can pass through the crossing empty roadway smoothly.
