近几年一些运输法开采的露天矿特点是强化采煤工作。有用矿物的备用储量直接关系到剥离工程量增大。倾斜和急倾斜煤层开拓时更有特殊的难度。主要是随采矿工程延深,剥离量总是增加的。 露天采矿延深过程中,为了备用储量随时有接续,利用控制露天开采区工作参数的方法是减少剥离量增加的方向之一。 在进行剥离工程效果的技术经济评价时,用生产剥采即在已定的生产期内剥离量与采煤量的比;对具体条件下有用矿物开拓开采,用剥离工程量的大小进行评估,还可认为其它条件相同时剥离量大小取决于露天采场工作帮倾角的大小。但是,实际上工作 In recent years, some open pit mining methods are characterized by intensive mining operations. The reserves of useful minerals are directly related to the increase of the amount of stripping works. Tilting and steep coal seam mining more special difficulties. Mainly with the deepening of mining engineering, the amount of stripping is always increased. In the process of open-pit mining, one of the ways to reduce the amount of stripping is to use the method of controlling the working parameters of the open-pit mining area in order to keep the reserve reserves at any time. During the technical and economic evaluation of the stripping engineering effect, the ratio of the stripping amount to the coal mining amount during the production stripping, that is, the scheduled production period; exploiting and exploiting the useful minerals under specific conditions, evaluating the stripping amount, It can be considered that the other conditions are the same when the amount of stripping depends on the size of the open pit work to help inclination. But actually working
