应城市金龙石膏矿区三维地质可视化模型的建立与应用

Establishment and application of 3D geological visualization model for Yingcheng Jinlong gypsum mining area

应城市金龙石膏矿开采已超过60 a,地下形成了大面积采空区,引发了多起地面塌陷地质灾害事故。为更直观地展示石膏矿区复杂的地质条件与矿体、采空区以及地面塌陷空间分布特征,以应城市金龙石膏矿区为研究区,在综合矿区已有的钻孔柱状图、剖面图、采空区分布图、地质灾害点分布图等资料的基础上,以Surpac软件为平台,构建了地质-矿山生产-地质灾害三维可视化模型,实现了地质灾害与矿山生产之间的三维可视化表达,为矿山开采、地质灾害监测预警、地面塌陷综合治理提供了技术支撑,对石膏矿区地质灾害防治具有重要的推广与应用价值。

Jinlong Gypsum Mine in Yingcheng City has been mined for over 60 a,forming a large area of goaf underground,which has caused multiple ground collapse geological disaster accidents.In order to more intuitively display the complex geological conditions and spatial distribution characteristics of ore bodies,goaf,and ground subsidence in the gypsum mining area,Jinlong gypsum mining area was taken as the research area.Based on the existing drilling bar chart,profile map,goaf distribution map,geological hazard point distribution map and other data in the mining area,a three-dimensional visualization model of geology mining production geological hazards was constructed using Surpac software as the platform.The three-dimensional visualization expression between geological hazards and mining production was achieved,providing technical support for mining,geological hazard monitoring and early warning,and comprehensive treatment of ground subsidence.It has important promotion and application value for the prevention and control of geological hazards in gypsum mining areas.
