露天矿线路限制坡度(i_p)对调节采矿工作制度具有重要意义。增大基建堑沟坡度,可使最大剥离量留在开采较后阶段完成。当i_p从30‰增到60‰时,有10～15％的剥离量可推迟完成,使采矿工作制度更稳定,不出现短时超载;特别是在开采初期,采矿工作线短,更是如此。此外,增大坡度以减少总的剥离量。使用自卸汽车运输时,螺旋道的坡度由
The slope limit (i_p) of open-pit mine lines is of great importance to the adjustment of the mining work system. Increasing the slope of the infrastructure trench will allow the maximum amount of stripping to remain at a later stage of mining. When i_p is increased from 30 ‰ to 60 ‰, 10-15% of the stripping amount can be postponed to make the mining working system more stable without short-term overload; especially in the early stage of mining, the mining working line is short, especially . In addition, the slope is increased to reduce the total amount of peeling. The use of dump truck transport, spiral slope from
