缓倾斜矿体的开采方法这种方法包括将矿体划分为盘区,沿装载进车道方向布置矿房进行回采,掘进盘区平巷和装载进车道,从装载进车道形成下部拉底空间,浇灌混凝土侧壁在矿房内构成人丁底柱,用凿岩爆破法落矿,放出爆下矿石后用胶结充填料充填采空区。为了靠减少构成人丁底柱的劳动量和提高矿房矿量的实收率以降低采矿成本,从相邻盘区的盘区平巷向待采矿房掘进装载进车
This method involves the division of the ore body into panels, the placement of mines in the direction of loading into the lane for recovery, the driving of the panels into lanes and their loading into the lanes, the loading into the lanes to form the lower floor space, Watering the concrete side wall in the mine constitute a person Ding Dingzhu, with the rock blasting demolition method, released after the ore blasting with cemented filling material filling gob. In order to reduce the cost of mining by reducing the amount of labor required to make the bottom pillars and increasing the recovery rate of the mine’s mines,
