马城矿区三维地质建模及开采影响因素分析

通过系统整理马城矿区相关地质资料及图件,应用3DMine软件建立了钻孔数据库和矿区的矿体、地表及构造等三维地质模型。结合矿区水文地质资料,分析了矿区构造、基岩破碎带以及地下水等因素对矿体和基建工程影响,为采矿设计单位进一步优化开拓系统提供了可靠依据,并对未来矿床开采过程中可能出现的问题,提出了在诸如加强水文变化监控、避开或封堵未封钻孔、加强主副井井壁支护等建议。

Analysis of Influencing Mining Factors through 3D Geological Modelingin Macheng Mining Area

Having listed systematically geological data and maps of Macheng mining area, we build the 3D geological model by means of 3Dmine software, which contains the drilling database, and the ore bodies, the surface and the structure of Macheng Mining. Combining with hydro geological data of Macheng mining area, analyzes the factors that impact on ore body and infrastructure projects, which include the structure of mining area, rock crushing zone and underground water, etc. The analysis provides reliable basis for the mining design units optimizing development system, and puts forward corresponding suggestions on possible problems in future mining process, such as to strengthen hydrological changes monitoring, to avoid or plug undrilled holes, and to strengthen the support of the sidewall of the main and auxiliary shaft, etc.
