铜街曼家寨采场盲矿体预测及其研究意义

Prediction of blind ore bodies in the Manjiazhai mining area of Tongjie and its research significance

铜街曼家寨矿床为矽卡岩型锌锡多金属矿床(以下简称“铜曼矿床”),矿体受地层、岩性、构造及变质作用复合控制,矿床成因复杂,以中小矿体居多。受探矿工程限制,部分隐伏矿体未得到揭露控制,即本文中的盲矿体。但实际开采过程中能够采出一定量的盲矿体矿石量,对矿产综合回收利用及生产效益的提升均能起到积极的作用。以往矿山对盲矿体预测做了一些研究工作,但主要围绕盲矿体的成矿规律进行总结分析,预测盲矿体赋存区域,根据盲矿采出量估算今后可能采出的盲矿体资源量。按照目前公司对技术工作的精细化要求,可以进一步探索盲矿体预测方法、总结经验,有效指导勘探工程及服务生产作业。

The Tongjie Manjiazhai deposit is a skarn type zinc tin polymetallic deposit(hereinafter referred to as the"Tongman deposit").The ore body is controlled by a combination of stratigraphy,lithology,structure,and metamorphism,and the genesis of the deposit is complex,with small and medium-sized ore bodies being the majority.Due to limitations in exploration engineering,some hidden ore bodies have not been exposed and controlled,which are referred to as blind ore bodies in this article.However,in the actual mining process,a certain amount of blind ore can be extracted,which can play a positive role in the comprehensive recovery and utilization of minerals and the improvement of production efficiency.In the past,mines have conducted some research on blind ore body prediction,but mainly focused on summarizing and analyzing the ore-forming laws of blind ore bodies,predicting the occurrence areas of blind ore bodies,and estimating the potential amount of blind ore body resources that may be extracted in the future based on the amount of blind ore extracted.According to the current company's refined requirements for technical work,we can further explore blind ore body prediction methods,summarize experience,and effectively guide exploration engineering and service production operations.
