摘要: 分析了厚松散层下多煤层开采沉陷的部分显著性特征。基于概率积分法提出了开采沉陷预计与初始地形相结合的矿区开采沉陷积水区分布预测方法,并开发出了开采沉陷预计软件。利用该软件预测分析了淮南潘集矿多煤层开采引起的地表沉陷积水区的时空分布演变过程,有效显示出了地表沉陷未积水区、浅水区、深水区的分布与开采进程之间的联动关系,对于高精度预计矿区开采沉陷有一定的参考价值。

关键词: 开采沉陷, 概率积分法, 多煤层开采, 高潜水位

Abstract: Some distinct characteristics of mining subsidence caused by multi-layers coal mining under thick alluvial is analyzed.The distribution prediction method of the surface mining subsidence ponding is proposed by combing the mining subsidence prediction with initial terrain,and the mining subsidence software is developed.The spatial and temporal evolution of mining subsidence ponding caused by multi-layers coal mining in Panji Mine in Huainan City is discussed.The relationship between the the distribution of the surface mining area,shallow ponding and deep ponding between mining process is studied.The above analysis results in this paper is good to improve the prediction precise of mining subsidence.
