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.
This paper introduces three methods of side-hole orebodies, 1) Pour line projection method: According to the ore body surface shape using the projection of the stereotyped projection depth of the ore body to find the projection range, and then the hole .2) ore axis Law: The first draft of the middle of the ore body projection of the horizontal projection, find the ore body axis, and then arranged according to the direction of the axis of the direction of the Ting account for the hole .3) Longitudinal projection method: see the control hole excavation hole conditions, Body boundaries, with this diagram combined with cross-section layout accounted for the hole.
