采矿场崩落下来的矿石,无论从采矿场底部的放矿漏斗直接装入矿车还是流入电耙巷道,也无论从回采进路的端部放出还是从各种溜井底部的漏斗闸门放出,都是借助矿石的自重自溜放出。即重力自溜放矿。重力自溜放矿是传统的放矿工艺,放矿时常出现“卡斗”“悬拱”,劳动强度大,材料消耗多,放矿能力小,特别是对粘性矿石常常放不下来等一系列严重缺 No matter whether the ores dropped from the mining yard directly from the ore funnel at the bottom of the mining yard or into the electrical rake lane are released from the end of the mining path or from the funnel gate at the bottom of each slipway, With the self-weight of ore self-release. That gravity self-slip ore. Gravity slip self-leaching is the traditional ore drawing process, ore caving often appear “hanging arch”, labor-intensive, material consumption, ore handling capacity is small, especially for sticky ore often can not let down a series of Serious lack
