METHOD FOR DUST-GAS SUPPRESSION AT MASS EXPLOSIONS AT PITS

摘要

The method for dust-gas suppression at mass explosions in pits in which over each well, in the zone of plastic deformations, this is equal to 4-8 radii of the well, one forms an additional layer with thickness 0.2-0.3 m of the rocks of fraction 0-10 mm, this is wetted by dust-gas suppression solution; at that over the second layer of the rocks formed one places polyethylene capsules or sleeves filled with coagulation agent at amount 30-50 l per well.
