为了分离金川二矿区井下充填管路引流洗管水,避免引流洗管水进入进路对充填体强度带来负面影响,二矿区通过科技攻关,研制应用了矿用充填导水阀,解决了充填过程中引流洗管水进入充填进路的问题,杜绝了接顶充填时的溢流现象,使进路保持完全接顶,保证了充填料浆浓度和充填体强度,降低了污染,节约了充填成本。
In order to separate Jinchuan underground mine filling pipe drainage pipe water, to avoid the flow of water into the pipe to infuse the negative impact on the strength of the body, through the scientific and technological research in the second mining area, the development and application of mining filling valve to solve the filling In the process of drainage pipe washing water into the filling of the road to eliminate overflow when the top-fill, so that the access to fully top, to ensure that the filling slurry concentration and filling strength, reduce pollution and save filling cost.
