摘要
深大露天矿的间断向半连续开采工艺过渡时，合理深度及半连续开采工艺的移设步距是两个重要的开采参数，对矿山的经济效果影响巨大，本文首次提出采用组合台阶单位体的开采来分析确定这两个重要的参数，得到的结论在霍林河煤矿的应用中取得了满意的结果，对其它类似矿山具有应用价值。
The reasonable depth and moving distance in the cyclic-flow technology are both importantmining parameters during transition from cyclic to cyclic-flow technology, which are much effectiveon the mine's economic benefits. In this article, the 'Group Bench Unit Body' rnethod for determinationof the both important parameters is pesented first of all. Use of this mecthod inHuolinhe Coal Mine has got a satisfactory result , and the method is also suitable to use for othersimilar mines.
