METHOD FOR CHARGING WELLS AT IMPLEMENTATION OF BLASTING OPERATIONS

摘要

The utility model relates to mining. A method for charging wells at implementation of blast operations includes operations of separate supply to the well of solid and liquid components of explosive substance, with formation of well column of the solid component of explosive substance to designed height of charge with placing the means of initiation. To increase power properties of explosive substances and effectiveness of explosion of the well charge in the well column made of solid component of explosive substance one forms axial cavity by leans of garland made of thin-wall closed with tightening vessels, those are partially filled with liquid component of explosive substance, and the means for initiation are placed in the axial cavity over the garland made of those vessels.
