摘要

尽快实现露天煤矿的内排,对缩短排土运距,降低生产成本具有积极的作用。针对倾斜煤层的特点,打破以往仅布置1组工作线的方式,通过布置2组工作线,即搭配开采不同剥采比的区域,并加速推进其中1组工作线,进而快速降深至露天煤矿境界附近的煤层底板,实现尽早内排的目的。对丰富倾斜煤层露天煤矿搭配开采方式具有积极意义。
        Implementing internal dumping of open-pit coal mine as soon as possible can shorten the transportation distance, which playing positive rolein reducing the production cost. According to the character of inclined seam, break the previous way of arranging only one set of working lines, through arranging two team workplaces, that is collocation mining with different stripping ratios are mined in combination. and speedding up one team workplace in order to make one team workline to reach the bottom of the seam soon nearby the boundary. This method can put internal dumping in open-pit coal mine as soon as possible.The method will play an active role in the match mining technology.
