摘　　要：随着露天矿井逐步开采,致使矿井及其周围出现大量采矿边坡、采坑、矿渣堆、采矿平硐、地裂缝等环境问题。为了查明地质环境问题类型及分布范围、规模,采用综合勘探技术,对其地质情况以及分布范围进行勘查,使用钻探技术对地层进行了揭露,揭露地表下20.0 m深度内的地层,主要为第四系、石炭系和奥陶系;利用槽探技术对地层进行了揭露,主要为第四系和石炭系,研究为后期矿山环境治理工作中矿渣方量计算和道路设计提供资料;并采用高密度成像探测技术以及Geogiga Rtomo全新高密度电阻率数据处理反演软件,得到了视电阻率剖面图和反演剖面图,确定其对应地质层位,并利用色像图变化特征确定地裂缝变化特征、采空区塌陷区等。研究为后期矿山地质环境的治理提供了技术支持。With the gradual exploitation of open-pit mines,a large number of environmental problems such as mining slopes,pits,slag piles,mining adits,and ground fissures have emerged in and around the mines.In order to find out the type,distribution scope and scale of geological environmental problems,this paper uses comprehensive exploration technology to investigate their geological conditions and distribution range,and uses drilling technology to expose the strata,mainly the Quaternary,Carboniferous and Ordovician.The stratum was exposed by trenching technology,mainly for the Quaternary and Carboniferous systems.The study provided data for the calculation of slag volume and road design in the later period of mine environmental control work.In addition,high-density imaging detection technology and Geogiga Rtomo′s new high-density resistivity data processing and inversion software were used to obtain the apparent resistivity profile and inversion profile,determine their corresponding geological horizons,and use the color image change characteristics to determine the ground fracture change characteristics,goaf collapse areas,etc.The study provides technical supporting for the later management of mine geological environment.
