摘要
运用端帮靠帮开采技术在白音华三号露天煤矿首采区西端帮采出压覆的煤炭资源,在露天矿端帮到界后,压缩端帮平盘宽度,快速采出所揭露的煤炭资源,并及时排土压覆形成道路,实现了该区域煤炭资源的高效利用。结果表明,白音华三号矿端帮靠帮开采技术的应用,充分提高了露天煤矿煤炭资源回收率并取得了很高的经济效益。
The steep end-slope mining technology has been used in the west end of the first mining area of Baiyinhua No.3 open-pit mine in the article,the efficient use of coal resources in the area has been achieved through the width of the flat plate of the end wall is compressed after the end wall of open-pit mine reaches the boundary,the coal resources are exposed quickly,and the road is formed by timely dumping and compaction.The results show that the recovery ratiohas been improved and high economic benefits have been achieved by application of steep end-slope mining technology in Baiyinhua No.3 open-pit mine.
