现阶段露天煤矿生产的特点是剥离工作量不断增大。在缓倾斜、倾斜和急倾斜煤层的矿区,当采煤量和剥离段推进量固定不变时,剥离岩石的工作带不断增大。在采矿工程推进到接近露天地表境界时,这种状况更为突出。因此,这时工作平盘宽度要缩小。剥离段推进量要减低,因为要保持设计计划的推进量,必须比预计的剥离量多剥离0.3～0.5倍的剥离量。因此,有的文章作者提出“由于剥离工作速度低,不能保持多工作平盘作业”。这种提法是没有根据的,这是我们的观点。库兹巴斯的一些露天煤矿在 The characteristics of open-pit coal mines at this stage are the stripping workload is constantly increasing. In the gently inclined, inclined and steep seam mining area, when the amount of coal and stripping section propulsion fixed, the stripping of rock work with increasing. This situation is even more pronounced as mining engineering progresses to near the surface level of the open air. Therefore, the work of the flat to reduce the width. Stripping segment propulsion volume to be reduced, because to maintain the design plan to promote the amount of stripping than the expected amount of more than 0.3 ~ 0.5 times the amount of stripping. Therefore, some article authors have suggested that “due to the low rate of de-duplication, it is impossible to maintain a multi-job flat-panel job.” This formulation is unfounded, this is our point of view.
