一、问题的提出在矿山生产中,平巷与平巷之间或平巷与斜巷之间需要掘进一些溜矿井。在溜矿井的设计中,给定溜矿井的起点和倾角以及到达另一巷道的大致位置。为了满足溜矿井对倾角的要求,在设计中不能给出溜矿井的平面方向。因此,在施工以前,需要根据设计要求和必要的测量资料解算出溜矿井的平面方向。为了提高掘进效率,斜溜井的掘进多采用自下而上的顺序,在掘进开始之前,就需要准确确定出溜矿井另一端的位置,所以,也是一个贯通问题。二、解算方法如图1所示,设在平巷与皮带运输巷之间掘进一溜矿井,起点为平巷中的A点,设计倾角为δ,终点位于皮带运输巷 First, the issue put forward In the mine production, between the lane and lane or lane and inclined lane need to dig some sloping mine. In slipped mine design, given the starting point and inclination of the slipped mine and the approximate location of the other lane. In order to meet the requirements of sloping mines, the plane direction of the sloping mines can not be given in the design. Therefore, before construction, we need to calculate the plane direction of the sloping mine according to the design requirements and the necessary measurement data. In order to improve tunneling efficiency, inclined chutes are mostly driven from bottom to top. Before the start of excavation, the exact position of the other end of the slippery mine needs to be accurately identified. Therefore, it is also a through problem. Second, the solution method shown in Figure 1, located in the lane and belt transport lane between the tunnel a slipped mine, starting point for the A point in the lane, the design angle of δ, the terminal is located in the belt transport lane
