MOUNTAIN ROCKS CUTTING METHOD Russian patent published in 1995 - IPC

Abstract RU 2046942 C1

FIELD: mining. SUBSTANCE: method provides for drilling boreholes, charging them with explosives and blowing it up. To increase quality of demolition of mountain rocks preliminary before charging boreholes with explosives transversal waves speeds are measured. Then their values are recalculated in terms of resistance of rocks to single axis pressure, in limits of which charge of explosives is concentrated. EFFECT: method allows to increase effectiveness of rocks demolition operations. 1 dwg
