随着采矿事业的发展,我国出现了一批使用无轨采、掘、运设备的矿山。为了便于无轨设备的自行出入,需要开拓地表通坑内或各采矿中段之间的斜坡道。因此,如何掘进斜坡道就成为使用无轨设备矿山建设的重要课题之一。一、斜坡道施工的几种方法综合斜坡道开拓方式,共有两种。一种是上坡式掘进,一种是下坡式掘进。当然也有两种方式在同一条斜坡道施工中都采用。下面是我国部分矿山曾经采用过的几种 With the development of mining industry, a number of mines in our country have emerged that use trackless mining, digging and transporting equipment. In order to facilitate the self-access of the trackless equipment, it is necessary to open a ramp in the surface pit or in the middle of each mining. Therefore, how to excavate the ramp has become one of the important topics in the construction of mine using trackless equipment. First, several methods of slope construction Comprehensive slope ramp development methods, there are two. One is uphill excavation, one is downhill excavation. Of course, there are two ways to use the same ramp construction. Here are some of our mines have used several
