对于采用汽车运输原矿的矿山,在原矿仓前设计卸矿平台,一般只需参考汽车行驶道路的最小平曲线半径,充分考虑地形,确定一个形状和尺寸均合适的回车场即可。正因为该设计简单,所以常被人们忽视,由此可能带来许多不良后果。 (一)较复杂情况下卸矿平台可能出现的问题 以××硫铁矿为例,该矿为大型露天矿,原矿规模300万吨/年,其中贫矿和富矿各为150万吨/年。在矿山总平面设计中,两种矿石的破碎厂房合并,其原矿仓也布置在同一侧的同一卸矿平台内,参见图1。
For mines that use motor vehicles to transport raw ore, designing the unloading platform in front of the ore mines generally only needs to refer to the minimum flat curve radius of the road on which the vehicle travels, taking full account of the terrain and determining a return yard of suitable shape and size. Because of this simple design, it is often overlooked, which may have many adverse consequences. (I) Possible problems in the unloading platform under complicated conditions Taking × × pyrite as an example, the mine is a large open pit mine with a scale of 3 million tons / year, of which 1.5 million tons of lean ore and rich ore each year . In the mine general graphic design, two types of ore crushing plants are merged, and their ore storage silos are also arranged in the same unloading platform on the same side, as shown in FIG. 1.
