摘　　要：用最大采场崩落影响高度到地表的安全高度小于矿体埋深来判断地面有陷落,并从产生陷落区的采场底部向地面圈定陷落区,研究表明该陷落区的判断方法比用最低开采深度圈定陷落区方法更加符合实际。The impact of maximum height of stope caving to ground safety height which is less than burial depth of the ore body is employed to judge subsidence of ground area and subsidence area is de- lineated from production collapse district at the mining bottom to the upper area. Study indicates that delineation method of subsidence area is at a higher degree corresponded to reality than method by lowest mining depth to delineated the subsidence area.
