| 摘 要： | 我国煤炭资源的开采已向深部延伸，深部开采将带来新技术上的难题，地表沉陷预测就是技术难题之一，浅部开采和深部开采引起的地表沉陷特点是不同的．结合实例以及力学分析，对深部开采引起的地表沉陷问题进行了研究，论述了深部开采的地表沉陷规律及特点，深部开采工作面的覆岩破坏，具有均匀、整体压缩、移动、变形的特点，地表移动变形连续、缓慢、周期长；提出参数修正的概率积分预测模型，来预测深部开采的地表沉陷，以指导我国的深部“三下”压煤的开粟．

| Abstract: | In China,the coal seam in the deep area is being developed,therefore,the subsidence prediction is one of the difficult technological problems.By mechanical analysis as well as case analysis,subsidence caused by the deep coal mining was studied.The results show that the subsidence movement of overburden layer is characterized by uniform and entire compression,displacement and deformation.The law of surface subsidence is that the surface deformation is continual and slow with a long last period of movement.Finally,the predicting method with amendable probability integral in deep coal mining was put forward. |
