【摘要】 程潮铁矿东区受地下开采的影响 ,地表已出现了不同规模的塌陷和错动。在地表布设 6 7个监测点进行了多年监测。通过对监测结果的分析 ,得出该矿区地表移动、塌陷的规律是 :随着采矿深度增大 ,矿体倾角变小 ,矿体厚度增大 ,地表移动、塌陷更加急剧的向西、向南北向扩展。更多还原

【Abstract】 Subsidence and disturbance of various scales have occurred on the surface of the East Zone in Chengchao Iron Mine, due to the influences caused by underground mining. Monitoring has been performed for several years through 67 monitoring points deployed on the surface. Analysis on the monitored results shows that displacement and subsidence expands more sharply westward, southward and northward with the increase in mining depth, decrease in orebody dip angle and thickening of the orebody.更多还原
