巴彦诺日公地区饰面石材花岗岩矿地质环境恢复治理研究

Study on the geological environment restoration and treatment of veneer dimension stone granite mine in Bayanorigong area

巴彦诺日公花岗岩大岩基中南部蕴藏了多处饰面石材花岗岩矿资源,适宜进行露天开采。在调查地质环境现状基础上,分析了矿山开采潜在环境影响,提出了矿区环境生态修复建议。研究结果显示,矿区环境地质条件中等,生态环境较为脆弱,开采中应采用表土剥离保护土地资源等方式,土地复垦主要方向为人工草地三等地。露天采场、废石场土地损毁程度达重度,表土堆放场、荒料临时堆放场、工业场地、矿区道路土地损毁程度均为轻度,通过覆土、播撒草籽恢复植被,土地复垦后应加强管护。

There are many veneer dimension stone granite mine contained in the south central part of Bayanorigong granite batholith.The ore body is exposed to the surface and is suitable for opencast mining.Based on the investigation of the current situation of geological environment,this paper analyzes the potential environmental impact of mining,and puts forward the suggestions of environmental and ecological restoration in the mining area.The study shows that the environmental geological conditions in the mining area is medium and the ecological environment is relatively fragile.Topsoil stripping should be used in mining to protect land resources.The main direction of land reclamation is the third-class artificial grassland.The degree of land damage in opencast and waste rock yard is severe.The degree of land damage in topsoil dump,temporary waste dump,industrial site and mining area road are mild.The vegetation is restored by covering soil and sowing grass seeds,and the management and protection are strengthened after land reclamation.
