采掘相向沿空掘巷动态分段围岩控制技术

Analysis on the surrounding rock control technology of dynamic segmentation for gob side entry driving

相向沿空挖掘巷主要布置在一些大型煤矿边缘中与上一区段采空区相邻或交界处。在对其实际挖掘过程中,可以根据整个煤矿的地质条件制定出科学、合理的挖掘方案,加强对采掘相向沿空掘巷挖掘全过程的控制工作,保证在实际挖掘过程中巷道具有较高的稳定性,提升巷道掘进的质量与安全性。基于此,文中对采挖相向沿空挖掘巷动态分段围岩控制技术进行了简单的分析。

The gob side entry driving is mainly located at the edge of some large coal mines and adjacent to the upper goaf. In the actual mining process, according to the geological conditions of coal mines, by determining scientific and reasonable development and mining plan and strengthening the management work during the tunneling of gob side entry driving, the higher stability in the actual tunneling process can be ensured, and the quality and safety in roadway tunneling can be improved. Finally, the surrounding rock control technology of dynamie segmentation for gob side entry driving was analyzed.
