强力锚杆锚索协调支护技术在深部矿井中的应用

Application of coordinate supporting technology of powerful bolt and anchor in deep mine

针对邢东矿深部矿井巷道变形大、支护困难的问题,通过现场调研发现,巷道围岩强度、地应力、支护形式及参数是影响巷道稳定性的主要因素。结合该矿的支护现状及地质条件,提出强力锚杆锚索协调支护技术,并选择合理的支护参数。实践表明,支护效果良好,实现了该矿主副暗斜井的长期稳定,降低巷道的返修率。

Based on the problems of deep mine roadway deformation and difficult support in Xingdong Mine,through field investigation,it was found that the surrounding rock strength,ground stress,supporting form and parameters of the roadway were the main factors affecting the stability of the roadway.Combining the support status and geological conditions of the mine,the coordinated support technology of strong bolts and cables was proposed,and reasonable support parameters were selected.Practice showed that the support effect was good,and the long-term stability of the main and auxiliary inclined shaft of the mine was achieved,and the repair of the roadway was reduced.
