In order to improve the recovery rate of coal mining and extractive ease tensions convergence issues, took Yunjialing mine 12,802 haulage gob no pillar protected roadway materials combined with high water ways as example to study the feasibility of the method. Studies showed that: the method making the stay roadway technology has been greatly improved, especially its solidification speed, early strength, increasing resistance fast, sealed gob good effect, good effect left lane as well as its large amount of water, the solid material with less, easy pumping, high degree of mechanization, low labor intensity, which showed good prospects for development.
