随着露天开采矿岩量的不断增加,排土场占地面积也不断增大。因而,在不适于农业种植的区域内设置高阶段排土场和尽量利用露天矿采空区排土是合理的。随着排土场总高度的增加,排土场变形的潜在危险性也增大。从而对确定排土场极限总高度和防护堤宽度准确性的要求也就提高了。防护堤宽度是由排土场可能塌陷(滑坡)棱柱体的总宽或局部宽度决定的。根据统一安全规程的要求,运输工具应当沿岩石可能塌陷(滑坡)棱住体内侧卸载。在实践中,经常出现 With the continuous increase of the open-pit ore, the area of ​​the dump site also increases. Therefore, it is reasonable to set up a high-level dump and to make the best use of the mined-out area of ​​open-pit mines in areas unsuitable for agricultural cultivation. With the increase of the total height of the dump, the potential danger of the deformation of the dump will also increase. Thus, the requirements for determining the total height of the dump and the width of the bank are also raised. The width of the berm is determined by the total width or local width of the prism that the dump may collapse (landslide). In accordance with the requirements of the harmonized safety regulations, the means of conveyance should be unloaded along the inside of the body where the rock may collapse (landslide). In practice, often appear
