【摘要】 本文设计了一种矸石堆的成堆方法 :在堆积若干年之后 ,后移一定距离重新堆积并将之前的矸石堆覆盖 ,这一方法在文 [1 ]的基础上使电费的值继续减少 ,并计算了两次成堆情况下不同出矸率对应的电费值 .更多还原

【Abstract】 This paper designed a method of heaping up gangue: after several year′s heaping, we restart to heap from a new point behind the first point and covered the gangue heap already exist. This way may reduce the cost of power on the foundation of paper . We calculated the cost of power in the case of different rate of producing gangue under the condition of two strokes heaped a hill of gangue.更多还原
