Coal injection sealing device Note 1, the use of coal seam water sealing is fast and simple. Just the job site waterways and sealing device connectivity, the sealing water sealing device is fully inserted into the borehole, at a certain pressure water tunnel sealing, a sealing device hose expansion to achieve sealing, water breaking coal. 2, seam sealing water can be reused several times after the injection relieved the pressure, sealing device can be recovered, remove sealing device. 3, sending plug sealing device and recovery operation with pressure sealing device is prohibited. 4, when the sealing is not allowed to work in front of people jobs. 5, sealing must be straight using do not discount the weight. 6, regulate the use of the good sequence valve (opening pressure should be greater than 1MPA), the pipeline must be a pressure gauge to monitor mine water sealing, pressure is higher than the working pressure of the water is prohibited, the job is completed to remove pressure water pipe water pipe sealing rubber expansion hole, a sealing device to be anhydrous relief, restitution, finishing out of spare sealing device. Grouting grouting sealing sealing device is suitable for use of coal or rock in the grouting, when water and subsequent plugging holes. Expansion pipe sealing by grouting pressure, safety valves, quick connectors and other components steel skeleton.
