| 摘 要： | 采用采空区数量、采空区上部岩体厚度、裂缝密度及裂缝集中度4 个指标, 对某铜矿采空区上部地表1～11 测线区域的稳定性进行灰色定权聚类分析。结果表明, 各测线区域均不稳定, 9 测线区域最不稳定, 这和地表变形情况完全吻合。

| Abstract: | For analyzing the stability of the ground above excavated area in the area of survey line 1～11 in a copper mine, four indexes, such as quantity of excavated areas, thickness of rock mass above excavated area, density of fracture and degree of fracture concentration are adopted in the method of Grey fixed weight cluster.The results, which are very close to the ground deformation, show that each area of the survey line is in an unstable state, and the most unstable area is survey line 9. |

| Keywords: | excavated area stability fracture height of caving zone grey fixed weight cluster |
