Abstract
FIELD: mining industry; applicable in underground mining of mineral deposits in masses with high initial horizontal stresses. SUBSTANCE: driven in laying and hanging walls are development workings. Driven along the boundary of the anticipated room from fringe drift is short cross-cut 5 from which cutting raise 6 is driven which is expanded into relieving cavity in form of slot. Drilled from end of cross-cut 5 to opposite corner of the room is opening 8 or two mutually perpendicular openings are drilled parallel to long or short sides of slot near boundaries of anticipated room. Then, slot is expanded in plan in form of similar rectangles by concurrent blasting of hole rings sunk from drilled opening (openings) parallel to long and short-sides to break ore layer. Length of slot is determined by the expression including width of slot and ratio of maximum horizontal stresses occurring in rock mass. EFFECT: reduced impoverishment of mineral in mining in stressed rock mass due to increased stability of enclosing rocks, increased mining intensity and cut down expenditures for formation of compensation and relieving cavities. 4 cl, 5 dwg
