摘　　要：为更加合理开发利用辽宁兴城马家沟花岗岩矿资源,结合其地质条件,先开展矿体特征、矿石特征分析;其次再从矿区水文地质、工程地质和环境地质方面出发,开展矿区开采技术条件研究。分析结果表明:矿区范围内为同一个花岗岩矿体,矿石类型包括灰白色中粒黑云母二长花岗岩(青山白)和浅肉红色中粗粒黑云母二长花岗岩(虎皮花)两类,其矿物成分由碱性长石、斜长石、石英、黑云母组成,且矿石结构、构造均较为简单;同时,矿区水文地质条件、工程地质条件简单,地质环境质量中等,矿区开采技术条件复杂程度划定为中等的矿床,属于以环境地质问题为主要的矿床(Ⅱ-3)。In order to develop and utilize the granite resources of Majiagou in Xingcheng,Liaoning more reasonably,and based on its geological conditions,the characteristics of the ore body and ore features will be analyzed first;Secondly,starting from the hydrogeological,engineering geological,and environmental geological aspects of the mining area,research on mining technology conditions will be conducted.The analysis results indicate that the mining area belongs to the same granite ore body,and the ore types include gray white medium grained biotite diorite(Qingshanbai)and light flesh red medium coarse grained biotite diorite(Hupihua).Their mineral composition consists of alkaline feldspar,plagioclase,quartz,and biotite,and the ore structure and structure are relatively simple;At the same time,the hydrogeological and engineering geological conditions in the mining area are simple,the geological environment quality is moderate,and the complexity of the mining technology conditions in the mining area is classified as a moderate deposit,belonging to the ore deposit(II-3)with environmental geological problems as the main focus.
