针对大采深高地压首采面地质条件,分析了锚网支护对回采巷道变形控制的可行性。通过锚杆、锚索协调作用分析,正确设计锚索的预紧力,可以使锚杆和锚索达到同步承载。通过矿压观测,证明锚网梁加锚索支护是一种合理的支护方式。
According to the geological conditions of the first mining face with large mining depth and high pressure, the feasibility of bolting and meshing support on deformation control of mining gateway is analyzed. Through the coordination analysis of anchors and anchors, the pre-tightening force of anchors can be correctly designed so that the anchors and anchors can be carried synchronously. Through the observation of rock pressure, it is proved that the anchor net beam and anchor cable support is a reasonable support method.
