我矿是1座采选能力为800t/d 的黄金矿山,采矿方法为向上水平分层充填法,因此充填作业在矿山生产中占有举足轻重的作用。要保证矿山生产的正常进行,就要进一步提高井下充填浓度,降底充填作业时间。但是该矿充填站在使用过程中存在充填浓度较低,不能满足井下生产对尾砂的需求的问题。每年注入井下的充填用水量为10万 m~3左右,过多的用水再次注入井下,充填中的部分泥浆沿着卸水井进入水仓,使主排水系统的设备运行时间延长,并
I mine is a gold mining capacity of 800t / d gold mining, mining methods for the level of stratification upward filling method, filling operations in mining production plays a decisive role. To ensure the normal production of mines, it is necessary to further improve the concentration of downhole filling, bottom filling operation time. However, there is a problem that the fill concentration of the mine filling station is low during use, which can not meet the demand of the tailings for underground production. Each year, the amount of filling water injected into the well is about 100,000 m3. Excessive water is injected into the well again. Part of the mud in the filling flows into the water tank along the unloading well to prolong the running time of the equipment of the main drainage system.
