一、问题的提出向下山巷道作倾斜联络巷,选用的方位不同,联络巷的坡度和长度也就不同。于是,就产生了一个问题,选用什么方位的联络巷,是坡度小而长度又最短的呢? 由几何学的原理知。一点到一直线的距离,以垂线为最短。但是,这一简单的原理在通向下山巷道的倾斜联络巷的设计和施工中,并没有被人们所应用,因为计算太复杂。本文对此计算公式进行推导,并提出了较简便的计算方法。
First, the issue put down the roadway to make contact with the inclined lane, the use of different orientation, the contact lane slope and length will be different. As a result, a problem arises. What is the connecting lane to use, which is small in slope and short in length? It is known from the principle of geometry. The distance from one point to a straight line is the shortest. However, this simple principle has not been applied in the design and construction of the inclined gateway to the downhill roadway because the calculation is too complicated. In this paper, the calculation formula is deduced and a simpler calculation method is proposed.
