angle of working slope
gongZUObang POJ一00工作帮坡角(angle of working slope)露天矿工作帮最上一台阶坡底线和最下一个台阶坡底线所构成的假想坡面与水平的夹角(见图)。工作帮坡角的大小,反映在采出矿石量相同条件下,要求剥离岩石量不同。一般工作帮坡角大,剥岩量少,反之便多。 工作帮坡角的计算公式为: 艺“ 声=aretan百二万一一~—一一一荞丁一 艺h are eota+乙召 l1\犷爷 工作帮坡角示意图 小一工作帮坡角;B一工作平台宽度; a一台阶坡面角汤一台阶高度式中笋为工作帮坡角(“);h为台阶高度,m;Q为台阶坡面角(。);B为工作台阶宽度,m。 中国金属露天矿工作帮坡角较缓,一般为8o一120,从20世纪80年代起,逐步采用陡帮开采。工作帮坡角可达200一250。 (蔡鸿起)
