摘要
该文根据土力学基本原理研究了矿井生产建设过程中 ,由于矿区含水层的疏排所引起的地面沉降的成因、机理和控制因素 ,并提出了相应的数学计算模型。为第四纪覆盖层巨厚且地下水丰富的平原矿区的地面沉降预测提供了理论依据 。
Based on basic principle of soil mechanics,the paper studies the genesis,mechanism and control factors of ground settlement produced by dewatering and drainage of aquifer in the construction and production procedure in mining area and put forward corresponding calculating model. It supplies coal mine,which is covered by large thickyness soil layer of quaternary period and abundant with ground water,with theoretical basis aimed at forecasting ground settlement.Also,it has a certain real significance for the prevention of geological hazards and protection of environment.
