摘要

The leakage test of granular cover is made by making use of model experiment method, and for different quantity of rainfall, the theoretical formula that on cover leak deepness and leak time for transforming opencast mining into underground mining is obtained by dimension analysis method, and the formula is checked bonding the reality of Shirengou open-pit mine. It is of great theoretical value and actual significance for determining the optimum thickness of cover for the mines transferring opencast to underground mining.
