摘要
为提高矿区开采面地表、河床位移变形监测效率,以某铁矿为研究对象,基于矿区地质、岩层、河床等参数,利用COMSOL Multiphysics软件构建矿区数值模型,对2个不同阶段的矿产资源开采及料浆充填过程进行模拟仿真,获取对应的地表、岸堤及河床位移云图,分析不同阶段位移变形特征;并通过无人机和无人船进行现场实测,与模拟数据成果进行对比分析,验证了基于数值模型的采空区地表、河床沉降位移解析数据成果的可靠性;同时可利用数值模型预测不同阶段开采面上覆岩层变形趋势,以可视化仿真模型对变形过程进行动态呈现,保障矿产资源安全开采。
In order to improve the monitoring efficiency of surface and riverbed displacement and deformation of mining surfaces in mining areas,this paper took an iron ore mine as the research object,built a numerical model of mining areas by using COMSOL Multiphysics software based on parameters of mining area geology,rock layer,and riverbed,and simulated the process of mineral resources mining and slurry filling in two different stages.The corresponding displacement cloud maps of surface,banks and riverbeds were obtained,and the displacement and deformation characteristics of different stages were analyzed.The field measurement was carried out by UAVs and unmanned ships,and the results of simulation data were compared and analyzed,which verified the reliability of the analytical data of the subsidence displacement of the goaf surface and riverbeds based on the numerical model.At the same time,the numerical model can be used to predict the deformation trend of overlying strata at different stages of mining surfaces,and the visual simulation model can dynamically present the deformation process to ensure the safe mining of mineral resources.
