摘要
论文首先针对拉斗铲倒推工艺的特点,提出了扇形转向和留沟缓帮转向两种方案,并通过露天矿生产工艺、转向期间的工作线长度、推进度、剥采比、煤炭产量、转向时间、外排量、剥离物运距、原煤运距、生产组织管理和设备效率等指标进行对比分析,得出采取留沟缓帮转向方案最为合理。
The thesis is aim at the characters of dumping with shovel, puts out two schemes for turning direction, and it makes a contrast with indexes, such as production process, working line, advancing degree, stripping ratio, coal production, transportation distance, management, equipment efficiency etc, at last, got a conclusion that the scheme to stay channel with gently slope is the most reasonable way.
