深部高应力软岩巷道联合支护技术研究

Study on the combined support technique of deep soft roadway with high pressure

随着矿井向深部开拓延深,巷道围岩条件更为恶化,巷道的掘进和维护更为困难,通过对鹤煤六矿深部高应力软岩巷道联合支护技术研究,采用锚网喷+锚索+壁后充填注浆联合支护技术,提高了支护强度,有效地控制了巷道变形,满足了安全生产的需要,为深部高应力软岩巷道支护探索出新路子。

With the shaft deepening,the conditions of surrounding rock become more bad,and the roadway excavation and maintenance more difficult.Through studying the combined support technique of deep soft roadway with high pressure in the sixth mine of Hebi Coal Industrial Company,the combined technique of shotcrete rockbolt mesh,cable anchor and backup and grouting was applied,which improved the support strength,controlled the roadway deformation effectively,and met the need of safety production.It provided a new way for the support of deep soft roadway with high pressure.
