Mining operation in Xingshan iron is just in the transient stage from the open-pit mining to underground mining. In order to understand mining ground pressure and drift deformation in the mine , 8 borehole stress meters and 4 convergence gauges are arranged in No. 4 and No. 5 mining entrance of-33m level. According to the monitoring results, the mining ground pressure in surrounding rock mass and deformation situation of drift are determined to improve prediction of ground pressure law in the mining area.This is of great significance for safety of the mining production.%杏山铁矿开采,处于露天转地下的过渡性阶段.为了解开采过程中采场地压及巷道变形规律,在-33m水平4,5回采进路中,布置8个钻孔应力计和4个收敛计对巷道围岩进行监测,并对监测结果进行分析,以确定采场围岩体中应力大小及巷道变形情况,更好地预测深部开采围岩地压活动规律,对矿山安全生产具有重要指导意义.
