侧伏矿体的布孔方法

本文介绍侧伏矿体的三种布孔方法,1)倾伏线投影法:根据矿体地表产状用赤平投影等方法求出矿体延深的投影范围,然后布孔.2)矿体轴线法:先编制矿体各中段水平投影图,求出矿体轴线,然后根据该轴线下廷方向布置占孔.3)纵投影法:根掘控制孔见矿情况,在纵投影图上圈定矿体边界,用此图结合剖面图布置占孔.

METHOD TO ARRANGE DRILL HOLES ON PITCHING OREBODY

This paper introduces three Kinds of methods to arrange drill holes on the pitching orebody.1).Projection method of plunge-line.According to orebody surficial attitude,we can obtained the projection range of deep-seated orebody by stereog-raphic projection, and then arrange drill holes.2).Axial-line method of orebody:At first work out the patterns of every level horizontal projection of orebody to find its axial-line,then arrange drill holes based on the downward- extending orientation of this line.3)Longitudinal projection method: According to orebodies in control drill holes,orebody boundaries will be delineated on longitudinal projection map and drill holes can be arranged by this map combined with exploratory profiles.
