宁武县南沟煤矿矿山地质环境现状及土地复垦措施

Present situation of mine geological environment and land reclamation measures in Nangou Coal Mine of Ningwu County

宁武县南沟煤矿为地下生产矿井,十余年的开采产生了一系列地质环境问题。通过野外地质调查和综合研究得出:现状地质环境问题为地裂缝群发育,含水层破坏和地下水位下降,工业场地、风井场地、矸石场、排矸场、道路及洗煤厂对地形地貌景观破坏严重,并压占损毁土地严重,采矿区土地塌陷损毁严重等,拟通过地裂缝防渗处理、削高填低,工业场地清理,并实施土地平整和客土覆土,再选择合适的土地复垦措施,恢复土地的原有功能,以期为井下煤矿提供生产、修复和保护的理论依据。

Nangou Coal Mine in Ningwu County is an underground production mine.More than ten years of mining has produced a series of geological environment problems.Through field geological investigation and comprehensive research,it was found that the current geological environment problems are the development of ground fissures,the destruction of aquifers and the decline of groundwater level,the serious destruction of landform and landscape by industrial sites,air shaft sites,waste dump,waste dump,roads and coal washing plants,the serious occupation of damaged land,and the serious collapse and damage of land in mining area.It was proposed to restore the original function of the land through anti-seepage treatment of ground fissures,cutting high and filling low,cleaning of industrial sites,land leveling and covering with guest soil,and then selecting appropriate land reclamation measures,so as to provide theoretical basis for production,repair and protection of underground coal mines.
