摘要
利用钻孔、测井、地震、测绘以及煤矿开采等多源数据,构建羊场湾矿区初始三维地质模型。利用宁东矿区覆岩“三带”高度及平面分布范围,构建煤矿开采后地表沉陷的模型。通过前后2个模型的对比可以展示煤矿采煤后的地层沉降程度和地表塌陷范围,分析地面塌陷的发展趋势,实现对宁东地区采空区预防治理工作的预警。
The initial 3D geological model of Yangchangwan mining area is constructed by using multi-source data such as drilling,logging,seismic,mapping and coal mining.Based on the"three zones"height and plane distribution range of overburden in Ningdong mining area,a model of surface subsidence after coal mining is constructed.The comparison between the two models can show the degree of strata subsidence and the range of surface subsidence after coal mining,analyze the development trend of surface subsidence,and realize the early warning of goaf prevention and control in Ningdong area.
