摘要
FIELD: mining.;SUBSTANCE: in compliance with one version, one or several wells are drilled to collector. Note here that every well comprises the main borehole with two or several side holes drilled from the main borehole. One or several blast charges are placed in two or several lateral boreholes. Blast charges are blown up to develop pressure pulses that partially break the rock between two or several lateral boreholes. Blasts are timed so that one or several pressure pulses from different lateral boreholes interact.;EFFECT: higher efficiency of rock fracturing.;22 cl, 13 dwg
