距离幂次方反比法在稍日哦金矿区资源量估算中的应用

An Application of Inverse Ratio Method of Distance Power in Estimation of Resource Amount of ShorRioh Gold Mining Area

稍日哦金矿床位于青海省玉树藏族自治州曲麻莱县麻多乡北部,巴颜喀拉山北坡,是大场金矿田的重要组成部分,处于加给陇洼和大场金矿床之间。稍日哦金矿床共圈定金矿体156条,矿体走向107°~140°,倾向南西,倾角15°~85°。矿体长7~773 m,控制深度49~370 m,矿体厚度0.55~23.82 m,平均厚度2.26 m。研究主要利用澳大利亚Micromine国际矿业软件有限公司的Micromine 2016.1版软件平台,建立了矿区内所有矿体的三维模型,并使用距离幂次方反比法进行了资源量估算,通过估算,区内共求得推断资源量金矿石量3129103 t,金金属量8180 kg,平均品位2.61×10^(-6)。

ShorRioh gold deposit is located in the northern part of Maduo Township,Qumarla County Prefecture,Qinghai province.The northern slope of the Bayan Har Mountains is an important part of DaChang gold deposit,which lies between Jiagilongwa and DaChang gold deposits.A total of 156 gold ore bodies have been delineated with a strike of 107°~140°and a dip of 15°~85°to the southwest.The length of orebody is 7~773 m,the controlling depth is 49~370 m,the orebody thickness is 0.55~23.82 m and the average thickness is 2.26 m.This paper uses Micromine 2016.1 software platform of Australian Micromine International Mining Software Co.Ltd.to build 3D model of all orebody in mining area.We are using the inverse ratio method of power of distance to estimate resource amount,according to the estimation.The gold ore and metal resources in the area are estimated to be 3129103 t,8180 kg and the average grade is 2.61×10^(-6).
