摘要
通过山西省采煤沉陷区综合治理项目,以解决北岩煤矿因煤炭开采产生的诸多地质环境遗留问题。多年来,采矿活动已引发地裂缝20多处,破坏土地总面积19987.39 m^(2),通过填埋地裂缝1101 m,恢复土地面积2.00 hm^(2);地面塌陷区6处,塌陷坑破坏土地利用类型均为耕地,通过表土剥离、土方回填、土方整平、土地翻耕、生物工程,治理地面塌陷总面积37695 m^(2),需回填土方63250 m^(3)。区域分布火区2个,采用钻孔间歇式注浆施工法进行注浆灭火,治理区面积约9000 m^(2)。通过对矿山地质环境的恢复治理,取得了较高的社会效益、经济效益和环境效益。
Through the comprehensive control project of coal mining subsidence area in Shanxi Province,we aim to address the many geological and historical issues caused by coal mining in Beiyan Coal Mine.Over the years,mining activities have caused more than 20 ground fissures,the total area of land damage is 19987.39 m^(2),by filling 1101 m cracks,the land area restored is 2.00 hm^(2).There are 6 ground subsidence areas,and the land use type destroyed by subsidence pits is arable land.Through topsoil stripping,earthwork backfilling,earthwork leveling,land ploughing and biological engineering,the total area of ground subsidence is 37695 m^(2),and 63250 m^(3) of backfill earthwork is required.There are two fire zones distributed in the area,and grouting is carried out by drilling intermittent grouting construction method.The treatment area is about 9000 m^(2).By restoring and managing the geological environment of mines,high social,economic,and environmental benefits can be achieved.
