摘要
基于二景和谐煤矿15#围岩力学性质差,巷道掘进及回采施工过程中出现围岩破碎现象,严重威胁着采掘施工安全,对此通过技术研究决定对15#煤层围岩物理力学参数进行测定,并对15103工作面回采期间应力区回风顺槽围岩提出了“注浆+U29型钢棚”联合围岩控制技术,通过实际应用效果来看,取得了显著应用成效。
Based on the poor mechanical properties of the surrounding rock of No.15 coal seam in Erjing Harmony Coal Mine,the phenomenon of surrounding rock fragmentation occurs during tunnel excavation and mining construction,which seriously threatens the safety of mining construction.Through technical research,it is decided to measure the physical and mechanical parameters of the surrounding rock of No.15 coal seam,and a"grouting+U29 steel shed"combined surrounding rock control technology is proposed for the return air channel surrounding rock of the 15103 working face during mining.Through practical application results,significant application results have been achieved.
