吉林省安图县某金矿区工程地质条件分析

Analysis of Engineering Geological Conditions in a Gold Mine Area in Antu County,Jilin Province

研究区地处长白山北麓甑峰岭,总体地势为东南高、西北低。区域断裂构造发育,空间展布上形成相互切割的构造格架,由老至新生成顺序为北西向→北东向→南北向。从岩石工程地质岩组特征、结构面特征、岩体质量、稳定性评价等方面分析,结合岩石物理力学性质测试结果,分析认为研究区工程地质勘查的复杂程度为简单型。

The research area is located at the northern foot of Changbai Mountain,Zengfeng Ridge,with an overall terrain of high in the southeast and low in the northwest.The regional fault structures are well-developed,forming a mutually cutting structural framework in spatial distribution.The sequence of generation from old to new is northwest→northeast→north-south.Based on the analysis of rock engineering geological characteristics,structural plane characteristics,rock mass quality,stability evaluation,and combined with the results of rock physical and mechanical properties testing,it is believed that the complexity of engineering geological exploration in the study area is simple.
