采场底部结构采场底部结构sill structure of stope  eaiehangd一bu Jiegou采场底部结构(5111 strueture of stope)矿石自崩落处借助重力、爆力或运搬设备,沿采场已采空间下运的.采场底部出矿巷道的组合。底部结构是采场结构的重要组成部分.它在很大程度上决定着采场的生产能力及其他技术经济指标。设计和选择采场底部结构的基本要求是,在保证出矿巷道稳定作业安全及需要的出矿能力的条件下,尽量降低底柱高度和采准工作量,简化结构,且易于施工。 底部结构随出矿巷道的类型、数量、规格、组合关系及出矿方法、装备而异。采场用深孔(中深孔)落矿时,底部结构通常由四部分组成:(l)受矿漏斗或受矿槽。即最上层(受矿水平)出矿巷道,用以汇集采场矿石于其底部的放矿口放人下部水平。(2)装矿巷道或嗣室。位于运输水平,用来将矿石装人矿车及其他运输容器中。(3)二次破碎巷道或中间出矿巷道(电耙道、铲运机装运巷道等)。位于受矿水平和运输水平之间。前者用来将大块矿石破碎到允许块度;后者则将受矿巷道放出的矿石集运到通往运输水平的溜井,并在其中进行二次破碎.(4)受矿水平、二次破碎水平及运输水平间转运矿石的巷道(漏斗颈、斗穿、出矿口、溜井等)以及通往出矿作业的联络巷道。采场底部结构也可以根据需要简化和变型。如当用浅眼落矿并在回采工作面进行二次破碎时,不设二次破碎水平,矿石由受矿巷道经斗颈、漏口流人运输水平的矿车。 底部结构可按不同特征分类,如按有无二次破碎水平、受矿巷道型式(漏斗式、堑沟式、平底式)、运搬方法和设备(重力、电耙、自行装运设备、震动放矿装置等)等。将各类巷道综合成多种结构,以适应不同的开采条件的需要。采场底部结构的发展趋势是简化结构,提高矿石的流通性,降低堵塞频率,采用大型自行出矿设备或连续出矿装备。 (史维祥)
