开采倾斜矿床时,应用高效率的自行设备是有根大困难的。因而,在开采米尔加里姆赛矿床时,建议采用下向梯段回采的房柱法方案,即 “双矿房开采法”[1,2](图1)。由图可见,采用这种方案时,矿房沿矿体走向布置。但是在每个矿房的底板,从下盘留出三角形水平段台,作为停放电铲和移动运输设备的工作面。此外,矿房底板的形状允许从上部矿房进行下部矿房的拉底。这时上部矿房底板的标高与下部矿房拉底的标高相同。这样,一套自行设备就可以供给两个相邻的矿房使用。根据一般看法,这种双矿房开采法,在很
Mining inclined beds, the application of high efficiency of their own equipment is difficult to root. Therefore, during the mining of the Mill Galimu deposit, it is proposed to adopt the method of pillaring and reclaiming the downer to the “double-chamber mining method” [1,2] (Figure 1). Can be seen from the figure, using this program, the layout of the ore body along the ore body. However, on the floor of each morgue, a triangular horizontal section is set aside from the lower section to serve as a face for parking power shovels and mobile transport equipment. In addition, the shape of the floor of the mine floor allows bottom mines to be pulled from the upper mines. At this time, the elevation of the upper part of the mine floor is the same as the elevation of the lower trough. In this way, a set of self-equipment can be supplied to two adjacent coal mines. According to the general view, this double mining house mining method, very
