摘要
为了解安徽省宁国市龙门萤石矿矿体外围及深部萤石矿资源储量情况,并为变更采矿权范围及矿山开采设计提供依据,开展以地形测量、地质测量、槽探、钻探等技术手段为主的外围勘查工作.总结了萤石矿区域地质及矿区地质特征;查明了本矿区萤石矿体数量、规模及产状等特征,明确了矿体严格受硅化破碎带(石英脉)控制;认为本矿床为水文地质条件简单、工程地质条件中等、环境地质条件中等的Ⅱ-1 型矿床.本研究对已查明萤石矿床的合理开采及矿山企业的未来规划具有重要意义,也可作为该区进一步扩大萤石矿找矿成果的重要基础资料.
Abstract
In order to understand the situation of fluorite ore resource reserves in the periphery and deep part of the ore body of Longmen Fluorite Mine in Ningguo City,Anhui Province,and to provide a basis for changing the scope of the mining right and the mining design,this paper carried out the peripheral exploration work mainly by the technical means of topographic surveying,geologic surveying,slotting,drilling and so on.The regional geology of fluorite mine and geological features of the mining area were summarized.The number,scale and production characteristics of fluorite ore bodies in the mining area were identified.And it was clear that the ore bodies were strictly controlled by the silicification crushing zone(quartz veins).It was considered that this deposit is a Ⅱ-1 type of deposit with simple hydrogeological conditions,medium engineering geological conditions,and medium environmental geological conditions.This study is of great significance to the rational exploitation of the identified fluorite deposit and the future planning of the mining enterprise.At the same time,the results can also be used as an important basic information for further expanding the fluorite ore in this area.
