FIELD: mining technology. SUBSTANCE: according to method, drilling of bore-hole rings is effected from conveying and ventilation drifts at distance from each other which is equal to pitch of rock lowering in immediate roof. In this case, long bore-holes in ring are brought to upper Weber's spaces in dome of caving or lowering rock. Short bore-holes are brought to lower Weber's spaces. After that, consolidating solution is delivered into bore-holes, and Weber's spaces are filled with this solution. In result of aforesaid operations, stability of rock is enhanced, fissures are closed, and water migration into underground workings and towards ground surface is prevented. EFFECT: higher efficiency. 2 dwg
