重物下放,有竖井重物下放,有斜井(坡)重物下放,本文仅限于探讨后者。 一、问题的提出 我院设计的斜坡重物下放装置中的一个实例,有关的几个主要数据为:双箕斗矿石下放,箕斗有效载重7.5吨,斜坡倾角22°30′,下放全长594米。等速发电反馈运行距离535米,发电反馈等效功率119千瓦,运行时间104秒,下放周期时间163.58秒。若矿山规模为75万吨/年,则每次下放的发电量为
Heavy objects down, a heavy shaft of decentralization, inclined shaft (slope) heavy objects down, this article is limited to explore the latter. I. PROBLEM PROBLEMS An example of the design of slope weight dropping device designed by our hospital is as follows: The double skip bucket ore is decentralized, the skip effective load is 7.5 tons, the slope inclination is 22 ° 30 ’, and the full length 594 meters. Constant speed power generation feedback running distance of 535 meters, generation feedback equivalent power of 119 kilowatts, running time of 104 seconds, down cycle time of 163.58 seconds. If the scale of the mine is 750,000 tons / year, the amount of electricity generated for each decentralization will be
