我矿380水平有一矿块根据生产安排需开采回收。由于它位于边缘区域,管路过长,又返高100米,再加.上上下中段同时用水,在一般的情况下,到达采场底部时的水压仅1(公斤/厘米~2);而钻机还要随采场逐层上移45米。显然,在整个矿块回采过程中水压无法满足钻机正常开动的需要。如另行构筑水池来提高压差或采购加压设备,都是不现实的。所以,我们决定采用组合式压力水箱,利用钻机压风给水加压,以保证钻机正常开动。如附图所示的这样一套装置仅花费了300多元,实践证明是适用、可靠的。其工作过程如下: 1.使风管闸阀2处于关闭位置,打开排气开
Mine level 380 mine has a mine to be recovered according to the production schedule. Because it is located in the edge of the area, the pipeline is too long, and then back to 100 meters high, plus the upper and lower middle section of water at the same time, in general, to reach the bottom of the stope when the water pressure is only 1 (kg / cm ~ 2) Drilling rig also with the stope up by 45 meters. Obviously, the water pressure can not meet the requirement of normal operation of the drilling rig during the entire mining process. It is unrealistic to build a pool separately to raise the pressure differential or to purchase pressurized equipment. Therefore, we decided to use a combination of pressure tank, the use of drilling rig pressurized water supply pressure to ensure the normal operation of the rig. Such a device as shown in the drawings only cost more than 300 yuan, which proved to be applicable and reliable. The working process is as follows: 1. Duct gate valve 2 is in the closed position, open the exhaust open
