| Abstract: | With anchor bolting support technology,the support of broken host rocks near geological structure was reinforced,the support of broken roadways host rocks affected by mining stree and coal pillars concentration stree was also reinforced.The self-supporting ability of roadway host rocks was enhanced.A new method of support was pointed out for controlling roadway host rocks in coal mines. |
