The Shandong TongRui Mining Technology Co., Ltd. about the anchor cable drilling process water seepage treatment for everyone:

During drilling, or after drilling when the blow hole, is blown out from the hole are some stone grains and gray or yellow pellet without dust hole seepage, rock dust is attached to the hole wall, this when the hole depth has enough water into high-pressure wind net, until blowing water;

If the hole is deep enough, although the impact is work, there is still footage, it must immediately stop drilling, pull out the drill, and then continue to wash the hole drilling, and so on, until the end.

Sometimes seepage hole large, stagnant water, blown out of the mud and gravel, paste this case the rock powder does not live in the hole wall, as long as the impactor, you can continue to drill.

If the seepage is too big, as well as submerged the anchor cable impactor, the impactor will automatically stop working, should pull out the drill pressure grouting.
