摘　　要：为了获得万年矿回采巷道围岩松动圈参数,现场采用多点应力法测试巷道围岩松动圈。通过对万年矿13278回采巷道矿压的动态监测,分析巷道围岩内部应力动态变化规律,得到了巷道围岩松动圈的分布情况。In order to obtain the parameters of the loose rock zone around roadway in Wannian mine,the measurement was made on the loose rock zone by in - situ multi - point stress test. Based on the dynamically monitor of the rock pressure of 13278 extraction laneway in the mine, the dynanfical change law of the stress in surrounding rock of the laneway was analyzed, and the distribution of the loose rock zone of the laneway was tound. These provide the theoretical basis for the supporting optimization of extraction laneway in this mine.
