以往设计的井下煤仓,下部漏斗是直线园锥形,这种形式的煤仓,容易堵仓。为解决这一问题,参考了冶金部门和通化局地面双曲线煤仓的经验,把一采区煤仓下部设计成双曲线漏斗形式;仓壁用混凝土浇注,钢屑砂浆抹面,经试用效果良好。该煤仓80年8月设计,9～10月施工,11月投产,已用四年,通过煤量45万吨,不堵仓。仓净径4.5米,高17米,容积200吨。双曲线漏斗高5米,下口直径0.9米,钢屑砂浆抹面厚3厘米。
Downhole coal bunker designed in the past, the lower funnel is a linear conical garden, this form of coal bunker, easy block warehousing. In order to solve this problem, referring to the experience of the hyperbolic coal bunker in the metallurgy department and the Tonghua Bureau, the lower part of the coal bunker in a mining area is designed as a hyperbolic funnel. The wall of the bunker is poured with concrete and the surface of the steel scrap mortar is tested. . The coal warehouse in August 1980 design, construction from September to October, put into operation in November, has been used for four years, through the coal 450,000 tons, not blocked warehouses. Warehouse net diameter of 4.5 meters, 17 meters high, volume of 200 tons. Hyperbolic funnel 5 meters high, the next mouth diameter of 0.9 meters, steel shavings plaster surface thickness of 3 cm.
