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.
