采矿场底部布置电耙道的方式,在金属矿山已被广泛应用。电耙道的宽窄,则与耙运距离、耙道高度、矿石安息角、采矿强度或电耙能力等因素有关。当采用单翼漏矿口耙道布置时,用下式进行计算(参看附图):
The way to arrange electric rake at the bottom of mining field has been widely used in metal mines. The width of the electric rake is related to the rake distance, the height of the rake, the rest angle of the ore, the strength of the mining or the capacity of the electric rake. When using a single spillway harrow track layout, use the following formula to calculate (see the figure):
