METHOD FOR BURYING TOXIC WASTE IN MINE WORKINGS Russian patent published in 1998 - IPC

Abstract RU 2118459 C1

FIELD: mining industry. SUBSTANCE: this can be used for burying industrial toxic waste in salt rock mass. According to method, initially chambers are created and they are divided by interchamber pillars. Bore-holes of large diameter are drilled. Containers with toxic waste are placed in these bore-holes. Bore-holes for location of containers with waste are drilled in floor of burying chambers. Made in salt mass over perimeter of chambers are relieving slots and their depth is not less than depth of bore-holes. After placing containers with waste in bore-holes, clearances between them are filled with liquid isolating material which is insoluble in water. Application of method adds safety to storage. EFFECT: higher efficiency. 3 cl, 3 dwg
