为解决露天矿采矿场中深孔内的积水排除问题,我们制作了以压气为动力的间断排水器(如图)。工作时将排水器下放到钻孔底部浸入水里,这时孔底的水靠自然水位经过排水器底部的渗水孔将盖在孔上的塑料阀片浮起,而进入到贮水器内,待水渗满后,操作人员从地面向贮水 In order to solve the problem of stagnant water in the deep holes in the open pit mining field, we made a pressure-driven intermittent drain (pictured). Drainage work will be placed under the bottom of the hole immersed in the water, then the bottom of the hole by the natural water level through the drain hole at the bottom of the hole will be covered in the plastic valve float, and into the reservoir, To be water seepage, the operator from the ground to the storage of water
