摘要
安太堡露天矿与东露天矿调整开采境界后,对于2个露天矿相邻端帮间压煤如何开采问题,通过露天矿内排过程中留沟,并比较是否将所有煤层全部采出,确定最终内排土场在端帮处留沟标高和煤层的开采层位。
After Antaibao Open-pit Mine and East Open-pit Mine adjust mining boundary,by leaving ditch in the process of open-pit mine drainage,and comparing whether all the coal seams extraction,the article determines the inner dump left ditch elevation and coal seam mining horizon of end slope.
