FIELD: mining. ^ SUBSTANCE: method includes drilling vertical main and additional wells, besides selection of explosive for charging of additional wells is done by value of explosive detonation speed identified from the ratio with account of explosive detonation speed for charging of additional wells D0, m/s; ultimate tensile strength of solid inclusion rocks, Pa and ultimate tensile strength of host rocks, Pa. Additional wells are drilled with depth with account of solid inclusion soil elevation in depth of the main wells, between which appropriate additional well is located - m; number of the main wells, between which according additional well n is located, and diameter of additional wells - dwellêé, m. ^ EFFECT: improved efficiency of crushing of various solid inclusions with account of the main properties of host rocks, inclusions and applied explosives. ^ 2 cl, 2 dwg, 1 ex |
