摘要
Abstract
In reserves calculation of solid mineral resources is always concerned with extrapolation of ore bodies.Profile and horizontal projection of mining levels of ore bodies are media for the extrapolation and the ore body is generally extrapolated along strike or dip of the ore body.According to control or non-control with the exploration workings the extrapolation is divided into the definite and indefinite types.The extrapolation is started from the exploration working-controlled margin of the ore body.The extrapolation length is <1/2 of the working interval for tip-push and 1/4 of the working for push.Thickness of the extrapolated ore body at any point must not be thicker than that at the starting point.The extrapolation is closely related to classification of reserves.Generally,the reserve of the extrapolated ore body belongs to reserves type 333.关键词
