摘　　要：以东北某矿的实际研究资料为例,用相似材料模拟实验方法,研究了倾斜煤层立井保护煤柱外开采条件下的工业广场沉降和井筒变形破坏机理;根据该矿工业广场地表移动观测站的观测数据,依据Helmert坐标变换方法给出了确定立井工业广场沉降变形模式的分析模型。基于该模型,通过对地表多次观测所取得的数据分析,验证了模拟实验结果的正确性。Take the reserch data of a mine in the northeast of our country for instance, by means of the test study of similar material simulation, the ground subsidence, deformation and damaged mechanism of the shaft were analyzed at the conditions of mining incline coal beside pil- lars. According to the principle of Helmert coordinate transform a theoretical analytical method is put forward by using survey data to determine the pattern of the subsidence and deformation. Baseon the way to analyze the survey data acquired from ground many times observations, the simulation test results have been verified. It provides a scientific basis for taking effective measures to prevent the shaft from damage.
