摘要: 以华胜煤业3#煤层3103 工作面回采顺槽为研究对象,针对该顺槽围岩支护困难的问题,采用数值模拟与工程
应用相结合的方法全面分析研究。研究结果显示,顺槽围岩采用锚杆锚索加钢带联合支护的方式,对围岩的稳定性控制
效果最佳,相关顺槽支护参数对类似矿井施工有一定的借鉴意义。

Abstract: Taking 3103 working face mining gateway of 3# coal seam of Huasheng Coal Industry Co., Ltd. as the research object,
aiming at the difficulty of supporting the surrounding rock of the working face, this paper used the method of numerical simulation
and engineering application to analyze and study comprehensively. The research results show that the method of bolt, cable and
steel band combined support is the best way to control the stability of the surrounding rock in the stope, and the relevant
supporting parameters can be used for reference in similar mine construction.

Key words: mining gateway; numerical simulation; gateway support
