山西吕梁山脉地带煤矿工作面地表沉降移动参数的分析与应用

为了掌握山区煤矿开采引起的地表与岩层移动规律,建立了崖坪煤矿11208工作面观测站,得到地表移动角量、动态变形和预计参数等;掌握地下开采引起的地表移动与变形规律;为吕梁山脉地表塌陷及损坏等级提供技术参数;为类似煤矿的安全生产、"三下"采煤、土地复垦与环境治理提供科学的依据。

Analysis and application of surface subsidence and movement parameters in the coal mine working surface in Lvliang Mountains of ShanXi Province

11208 observation station in Yaping coal mine is built in order to assembling the movement rules of the surface and rock seams caused by mining exploitation in mountain areas. Surface movement angle parameters, dy-namic deformation and prediction parameters obtained are helpful to find out rules of surface movement and deforma-tion. All the datum provide technological reference for surface subsidence and destruction in Lvliang Mountains and provide scientific guidance for relative safety production in coal mines, minings under water, railways and buildings, land reclamation as well as environmental improvement.
