一、问题的提出回采工作面运输平巷通常以溜煤眼的形式与采区运输上山相连接。在煤层群联合开拓的采区,这类巷道布置方式更为普遍。因此,溜煤眼贯通是经常性的工作。这类贯通问题就是在水平巷道和倾斜巷道之间求解具有一定设计坡度的倾斜巷道。目前,有些计算方法可解算,但计算工作较繁琐。考虑到这类贯通只要满足生产要求(即煤的自溜),并不需要严密的计算,用图解法即可解决。二、图解法的实质图解法就是在一张比例尺较大的平面 First, the problem raised Face mining lane usually ladle coal mining in the form of mining and transportation up the mountain connected. Coal mining in the joint development of the mining area, the arrangement of such roadways more common. Therefore, slippery coal eye through is a regular job. This kind of penetration problem is to solve the inclined roadway with a certain design gradient between the horizontal roadway and the inclined roadway. At present, some calculation methods can solve the problem, but the calculation is cumbersome. Taking into account the penetration of such as long as the production requirements to meet (that is, self-slip coal), does not require rigorous calculations, with graphic solution can be solved. Second, the graphic method of graphic method is a larger scale in a plane
