西藏雄村铜(金)矿地质灾害危险性综合分区评价
RISKS EVALUATION OF GEOLOGICAL HAZARD OF XIONGCUN COPPER-GOLD DEPOSIT IN TIBET
【摘要】 将勘探开发区划分为小区块评价单元,从地质灾害基础因子、响应因子、诱发因子分析入手,选定地形地貌、植被、岩性、地质构造及周边地震活动、地质灾害现状、预测地质灾害的危险性、人类工程活动为雄村铜(金)矿地质灾害综合分区定量评估因子,由此求得各区块的灾害因子综合量值。按危险性分区阀值将各评价区块最终归并为地质灾害危险性大、中等和小3个级别分区。
【Abstract】 The paper divides the exploration area into small subdivisions evaluation sections,starts the analysis of the basic factors,response factors and inducing factors of geological hazards,chooses topography and physiognomy,vegetation,lithology,geological structure,circumjacent seismic activity,present situation of geological hazards,forecast of geological hazard risks,and engineering activities as the quantitative evaluation factors of combined evaluation of Xiongcun Copper-Gold Deposit geological hazards,and hence calculates the synthetical magnitudes of hazard factors of each section.All the evaluation sections fall into the three divisions(top risk,medium risk,low risk) according to the sectional thresholds of the geological hazard risks.
【Key words】 geological hazards of mines; hazard factors; assessment method of magnitude synthesis; sectional evaluation of geological hazards; Xiongcun; copper-gold deposit;
