露天矿边坡概念 露天开采与地下开采不同,它是从地面开掘露天沟道进行采矿作业的。开采时,需要把已确定开采的矿岩划分成一定厚度的水平分层,由上而下以阶梯状逐层向边界推进。这些阶梯状的工作面叫做台阶。露天采煤场周边由台阶组成的斜坡,称为露天矿边坡,见下图。 在垂直露天 Open Pit Slope Concept Open pit mining is different from underground mining, which is the mining of open-air channels from the ground for mining operations. Mining, the need to mine the ore has been classified as a certain thickness of the level of stratification, from top to bottom in a step-by-step ladder to the border. These stepped work surfaces are called steps. Surrounding coal mines around the slope formed by the stairs, known as open pit slope, see below. Open in the vertical
