山西矿山地质灾害分布特征研究

Study on distribution characteristics of geological hazards in Shanxi Mines

山西矿产资源丰富,矿山数量众多,长期的采矿活动给全省地质生态环境带来了严重破坏,造成了严重的矿山地质灾害。研究发现,山西矿山地质灾害以地裂缝和地面塌陷为主,崩塌和滑坡灾害主要以小型为主,地面塌陷以小型和中型为主,地裂缝以中型和大型为主。煤矿山、铝土矿山、铁矿山地质灾害均主要以地裂缝和地面塌陷为主,铜矿山地质灾害主要以崩塌为主。矿山地质灾害以小型和中型地质灾害为主,大型地质灾害以地裂缝为主,小型地质灾害以地面塌陷为主,中型地质灾害以地裂缝和地面塌陷为主。煤矿山和铝土矿山地质灾害均以小型地面塌陷和大型地裂缝为主,铁矿山地质灾害以小型地面塌陷为主,铜矿山地质灾害以小型崩塌为主。地裂缝和地面塌陷主要分布在晋城和阳泉矿区,滑坡灾害主要分布在离柳、西山、乡宁、汾西矿区,崩塌主要在大同、离柳矿区。

Shanxi is rich in mineral resources and numerous in mines.Long-term mining activities have caused serious damage to the geological and ecological environment of the province,resulting in serious mine geological disasters.The study found that the geological disasters in Shanxi mines are mainly ground fissures and ground subsidence.The collapse and landslide disasters are mainly small,the ground collapse is mainly small and medium,and the ground fissures are mainly medium and large.The geological disasters of coal mines,bauxite mines and iron mines are mainly caused by ground fissures and ground collapse.The geological disasters of copper mines are mainly collapse.Mine geological disasters are mainly small and medium-sized geological disasters,large-scale geological disasters are mainly ground fissures,small geological disasters are mainly ground subsidence,and medium-sized geological disasters are mainly ground fissures and ground collapses.The geological disasters of coal mine hills and bauxite mines are mainly small ground collapses and large-scale ground fissures.The geological disasters of iron mines are mainly small-scale ground collapses,and the geological disasters of copper mines are mainly small collapses.The ground fissures and ground subsidence are mainly distributed in Jincheng and Yangquan mining areas.The landslide disasters are mainly distributed in Liliu,Xishan,Xiangning and Fenxi mining areas,and the collapses are mainly in Datong and Liliu mining areas.
