掘进巷道过陷落柱支护方式优化

Optimization of Support Mode of Driving Roadway Through Collapse Column

赵家山煤业有限公司2106皮带顺槽过DX26陷落柱期间顶板管理困难,需对原支护进行优化,采取了锚网带索+工字钢的加强支护措施,有效提高了围岩稳定性,保证了巷道过陷落柱期间的安全。

During the period when the 2106 belt of Zhaojiashan Coal Industry Co.,Ltd.passes through the DX26 collapse column,the roof management is difficult,so the original support needs to be optimized,and the strengthening support measures of anchor mesh and cable+I-steel are adopted,which effectively improves the stability of the surrounding rock and ensures the safety of the roadway during the period of passing through the collapse column.
