伊敏河露天矿进入淤泥区开采后,发生多次陷车陷铲事故,对此,在工作面布置、电铲站立水平和段高选择、采掘程序安排、推进方式、淤泥的运输和排卸等方面采取相应措施后,解决了深度小于的淤泥用电铲采掘的问题,对深度大于的淤泥采掘问题,尚需进一步研究。 20 m 20 m Yimin open-pit mine into the mud area after the occurrence of a number of trapped trash shovel accidents, which, in the face layout, the power shovel level and segment height selection, excavation program, the way to promote the transport and dumping sludge And other aspects of the corresponding measures to solve the depth of less than the shovel shovel mining problems, the depth of more than the problem of mines, the need for further study. 20 m 20 m
