摘要
丰山铜矿矿岩稳固性差，变化较大，且采场位于高山陡坡之下，属于高应力集中区，巷道支护困难。根据该矿矿岩条件，对其分段碎石胶结充填法的巷道支护进行了试验研究，采用了灵活多变的支护形式和支护参数，取得了较好的效果。
At Fengshan copper mine,the stability of ore and rock was poor and varied, and the stopes were located under the steep slope of high mountain, where the high stress was concentrated. It was difficult,therefore,to conduct the excavation support. According to the conditions of ore and rock in this mine,the authors made an experimental study on the excavation support in the sublevel waste-cemented fining, adopted the flexible supporting pattern and parameters,and obtained a better result.
