沿空留巷在形成过程中需要经受掘进和两次回采的扰动,维护难度远非常规回采巷道所能比。通过对沿空留巷围岩控制机理以及加固技术研究的基础上,针对某矿24207工作面的实际地质条件,提出针对该工作面胶带巷的沿空留巷的加固技术。经过矿压观测对留巷表面位移变化进行分析,结果表明,留巷在工作面回采期间是稳定的。研究结论对于进一步推广煤矿的沿空留巷技术具有指导意义。 Gob-side entry retaining in the formation process need to withstand the excavation and two mining disturbance, maintenance is far more difficult than conventional mining roadway. Based on the study of surrounding rock control mechanism of gob-side entry retaining and reinforcement technology, aiming at the actual geological conditions of 24207 working face in a mine, the reinforcement technology of gob-side entry retaining for this work face is put forward. The result of rock pressure observation shows that the displacement of retaining laneway is stable during the mining face. The conclusion of the study is instructive to further promote the technology of gob-side entry retaining in coal mines.
