Based on water burst in vertical shaft construction, according to traditional construction technology, grouting pad was used to stop water, due to the long time of concrete setting, led to the low efficiency of vertical shaft construction, increased the construction period, lowered the production of the mine. Liangbei Mine introduced the new technology, reserved rock grouting method, which eliminated the problems of traditional technology, and provided experience for similar condition.
