采用水砂充填法采矿时,经常要排出大量的沉淀后的淤泥砂,因而在排泥系统中都要设置排泥仓。排泥仓工作时是一个两端密封的高压仓,通过进水与排水管道输送污泥。仓内工作压力取决于排放高度。仓体截面形状有园形及拱墙形两类,本文仅论述拱墙式(图1)泥仓的计算。排泥仓承受有泥浆自重、围岩压力、外水压力等外部荷载和由最大排泥高度而定的排泥仓工作压力。因泥仓一般均选建于围岩赋存条件比较好的地层中,故外部压力不大,常可略去,
When using water sand filling method mining, often to discharge a large amount of silt after sedimentation, sludge discharge system should therefore be set in the silo. Dump silos work is a sealed at both ends of the high-pressure storage tanks, sewage and sewage pipes through the transfer of sludge. Work pressure inside the warehouse depends on the discharge height. The cross-sectional shape of the warehouse has two kinds of garden-shaped and arch-shaped wall, this article only discusses the calculation of arch wall (Figure 1) silo. Sludge tank to bear the weight of mud, rock pressure, external water pressure and other external loads and by the maximum discharge height of sludge discharge chamber working pressure. Due to the general selection of silt were built in the surrounding rock formation conditions better strata, so the external pressure is not, often can be omitted,
