矿山井下矿仓、煤仓的储存和吞吐是矿业生产过程中的一个重要环节,是整个生产运输过程中不可缺少的重要组成部分,它对各矿的生产能力起着决定性的作用。特别是随着综采机械化程度的不断提高和采区集中生产的不断实现,矿仓的容量逐渐增大,使用效率越来越高。由于原煤或矿石多是经下端为锥形漏斗的矿仓依靠自重流动输送,在输送过程 Mine underground storage, storage and throughput of coal storage is an important part of the mining process is an indispensable part of the entire production and transportation process, which plays a decisive role in the production capacity of each mine. Especially with the continuous improvement of mechanization of fully mechanized mining and continuous realization of concentrated production in the mining area, the capacity of the ore storage is gradually increased and the use efficiency is getting higher and higher. Due to the coal or ore mostly through the lower end of the funnel hopper hopper rely on gravity transport flow in the transport process
