| 摘 要： | 露天采矿机结构特点独特,可对煤层及夹矸精确开采,从而减小煤损和混矸.为了确定采矿机合理的选采厚度,基于采矿机切削滚筒的实际轨迹,建立了煤损与混矸模型,并给出了选采效果关键评价指标一含矸率和毛煤热值的计算公式,得出露天采矿机选采效果与煤层的煤层总厚度正相关,与大夹矸总层数及小夹矸总厚度成负相关.通过对选采厚度的影响因素分...

| Abstract: | Aiming at the situation of being unique in structural features of the surface miner,we can accurately separate the coal from gangue to decrease the los of coal and decrease the mixing degree of coal and gangue.To reasonably determine the mining thickness of surface miner,we establish a coal loss and gangue mixing model based on the cutting roller track of the miner to figure out the key index and the formula for the determination of thickness and for the calculation of shale content and the calorific value ... |
