萍乡安源煤矿地表移动变形分析

Analysis of Surface Movement Deformation in Anyuan Colliery

安源煤矿创办于1898年,是享誉全国的百年老矿,具有煤层层数多,煤层分布不稳定,煤层结构复杂等特点。该矿由于长期大范围开采,受采动影响,井田范围内地表发生不同程度的下沉,不仅破坏了地形地貌景观,也影响了地面建筑安全。通过收集矿区钻孔及开采数据,对安源煤矿地表移动变形进行分析计算,为该矿安全开采和地质环境保护提供依据。

Aiming at the subsidence of the ground surface caused by mining in mine field of Anyuan Colliery,which not only destroyed the landform and landscape,but also affected the safety of the ground buildings,the author makes an analysis and calculation of the surface movement and deformation through collecting the data of drilling and mining,which can provide the basis for the safety mining and the protection of geological environment.
