Study on geological environment characteristics and ecological restoration of a mine in Mengxi Town,Guizhou Province
The study area is located in the slope area of transition from Yunnan-Guizhou Plateau to Xiangxi Hills and Sichuan Basin.The outcrop strata include Qingshuijiang Formation of Qingbaikou System to Niutitang Formation of Cambrian system and the fourth system.The characteristic period of the seismic response spectrum is 0.35s,and the regional stability is good.After many years of mining in the mining area,the geological environment problems are manifested as mine geological disaster,underground aquifer destruction,mine landform landscape destruction,land resource occupation,surface water pollution and so on.The scheme of lattice anchor slope protection + retaining wall + cut-off drainage ditch + demolition of mine abandoned building + installation of mine shed + green restoration is adopted for the restoration of mine ecological environment.Better ecological,social and economic benefits can be obtained through the restoration and treatment of mine geological environment,and the ecological virtuous cycle can be promoted.
