以熊耳山地区青岗坪金矿为研究对象,通过与1989年1:1万土壤地球化学测量结果进行对比得出太华群地层中的蚀变破碎带产出位置、规模与地球化学异常相吻合,找矿效果明显,估算出金矿储量。根据矿山生产规模、服务年限、主要税费等技术经济指标对青岗坪金矿进行工业价值评价,推算出该矿预期可获1278.59万元的年利润,投资利润率为51.3%,静态投资回收期为1.8年,经济效益较好。
Taking the Qinggangping gold deposit in Xiong’ershan area as the research object, by comparing with 1: 10000 soil geochemical measurements in 1989, it is found that the location, scale and geochemical anomaly of the altered crust in the Taihua group strata Anastomosis, prospecting effect is obvious, estimated gold reserves. Based on the technical and economic indexes of the Qinggangping gold mine, such as the scale of production, service life and main taxes and fees, it is estimated that the mine is expected to receive an annual profit of 12,785,900 yuan with an investment profit rate of 51.3%. The static investment recovery The period of 1.8 years, the economic benefits are better.
