河北复杂矿区中金矿地质的勘探及开采技术研究

Geological exploration and mining technology of gold deposits in Hebei complex mining area

河北冀西地区是我国浅成低温热液脉矿床主要分布区之一。河北冀西地区地质条件异常复杂,其中的西石门金矿位于太行山中北-阜平幔枝构造轴部,在麻棚岩体东南侧,矿体横向变化明显,外延尖灭无规律。由于二维地质研究图缺乏直观可视性和设计人员对矿体赋存形态的不明确导致开发该类型金矿时存在的效率低、贫化严重、资源浪费的现象的出现。本文针对这一情况,利用前人已有的研究资料对西石门金矿矿体形态进行的分析,利用3DMINE建立三维地质模型,并分析其在采矿设计、数值模拟方面的应用。

Hebei West Hebei Province is one of the main distribution areas of epithermal epithermal deposits in China. The geological conditions of Hebei Hebei West area is very complex, including the West Shimen gold deposit is located in the north of Taihang Mountain - axis of Fuping mantle branch structure, in the southeast of the Mapeng intrusion, the lateral variation of orebody is obvious, the extension of piching. Due to lack of visual designers and two-dimensional geological research of ore body shape is not clear to the development efficiency of＇this type of gold deposit at low dilution, using 3DMINE to establish three-dimensional geological model, and analyze the simulation application in mining design, numerical.
