我矿主井因放矿漏渣及井壁渗水等影响,井窝泥水粉矿堆积物需要经常清理。1982年之前,采用人工装车,通过斜坡道、副井提到地表,排放至废石山。这种排放方式既费工费时,影响井下文明作业,又浪费一定资源。之后,虽经一定的改进,但效果均不理想。1987年,我们对整个泥浆排放系统进行了改进,取得了良好的效果。具体作法是:在-183米中段砌筑一容积为90米~3的泥浆沉淀池。井下水窝处(-210米)设置泥浆罐。泥浆通过输送管排至沉淀池。在管子出口处串接两个气水减压分离装置,该装置可自动利用重力和速度将空气和泥浆水分
Due to the influence of mine leachate and water seepage on the borehole, the mine shaft of main mine needs to be cleaned regularly. Prior to 1982, artificial loading was adopted, surface was referred to by ramps and auxiliary wells, and discharged to waste rocky mountain. This mode of discharge is not only a waste of time and effort, affecting underground civilization operations, but also a waste of resources. After some improvements, but the effect is not satisfactory. In 1987, we improved the entire mud discharge system and achieved good results. The specific approach is: in the mid-183 meters masonry volume of 90 m ~ 3 mud sedimentation tanks. Downhole waterloo (-210 meters) to set the mud tank. The mud is discharged to the sedimentation tank through the delivery pipe. In the pipe outlet in series two gas-water decompression separation device, the device can automatically use the gravity and velocity of air and mud water
