布朗斯威克(Brunswick)矿山(12号矿井使用沿走向的分层充填法开采)每日生产矿石8400吨。因尾砂过细和含有很高的黄铁矿物,故选用了该矿6号露天坑的剥离廢石作为充填料。充填用的廢石先经破碎、运输、和通过错综复杂的充填井和鑽孔网路,输送到充填工作面。即使一次充填高度较高,带有振动的无轨设备多次在充填面上行走,以及凿岩设备用水的渗透作用,其充填体的最终密实程度是一种中等的密度。当装矿操作时,建立严格的操作标准,以减少从廢石充填体中对矿石的贫化。最后对廢石充填与一般尾砂充填的强度、顶底盘的控制、贫化和经济等问题作了比较。
The Brunswick mine, which is mined with a directional stratification charge, produces 8400 tonnes of ore per day. Due to the tailings too thin and contains high pyrite, it is used in the mine No. 6 open pit peeling stripping waste as a filler. Filling waste rocks are crushed, transported, and transported to the filling face through intricate filling and drilling networks. Even with a high filling height, the vibrating trackless device travels several times over the filling surface and the infiltration of the rock drilling equipment with water, the final density of the filling body is a medium density. When loading operations, stringent operating standards are established to reduce depletion of ores from waste rock fillings. Finally, the paper compares the strength of the waste rock filling with the general filling of tailings, the control of top chassis, depletion and economy.
