摘　　要：论文基于显德汪矿跨上山开采项目,介绍了松动圈的测试原理、测试方法,测试过程等。得出了破碎巷道合理的松动圈范围,为确定合理锚杆支护参数提供了依据,为相似条件巷道的松动圈测试提供了实践。并介绍了控制松动圈厚度的控制方法,对井下支护设计具有借鉴意义。The subject base on cross uphill mine in Xian De Wang Mine of Xing Tai. The thesis introduced loose circle test principle, test means and test process. At last, we know proper range of the loose circle. It supply basis for determine supporting and loose circle testing of similarity roadway. At last thesis introduce the control mode of loose circle thickness. Thesis has use for reference mine supporting.
