SD法在湖北大冶鸡冠嘴铜金矿床资源储量核实中的应用

THE APPLICATION OF SD METHOD IN MINERAL RESOURCES RESERVES CALCULATION IN THE JIGUANZUI COPPER-GOLD DEPOSIT,DAYE,HUBEI PROVINCE

SD法是一种全新的储量计算和审定方法 ,是我国使用的三大储量计算方法 (传统法、克里格法和SD法 )之一。根据国土资源部的指示和要求 ,湖北三鑫金铜股份有限公司和北京恩地科技发展有限责任公司共同对矿区的 13条勘探线、2 0个矿体、16个中段的资源储量运用SD法进行了全面的复核计算 ,成功地确定了鸡冠嘴铜金矿矿床 - 16 0～ - 170m、- 170～ - 4 70m、- 4 70m以下铜和金的保有储量。

SD method,one of three reserves calculation methods like geometry,Krige and SD methods in China,is a new mineral resources reserves calculation and examination method. According to the directive and demand of the Ministry of Lands and Resources,Beijing SD Science and Technology Development Co.,Ltd. and Hubei Sanxin Gold and Copper Co.,Ltd. used SD method to calculate mineral resources reserves of thirteen exploration lines,twenty ore bodies and sixteen levels in the Jiguanzui ore district. Finally,Cu and Au extractable reserves between -160m and -170m,-170m and -470m,and beneath of -470 in the Jiguanzui Cu-Au deposit had been confirmed effectively and successfully.
