An Application of Inverse Ratio Method of Distance Power in Estimation of Resource Amount of ShorRioh Gold Mining Area
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 3 129 103 t,8 180 kg and the average grade is 2.61 × 10-6.
