摘要
The invention relates to the mining of large-block stone from rocks in open pits using drilling and blasting operations. A mixture is claimed for the manufacture of a transmitter and attenuator of the blast impulse of an explosion in a blast hole, which transmitter and attenuator is in the form of a nonexplosive substance and can be placed between fuses with an explosive substance having a high detonation rate and the walls of blast holes bored along the edges of a block of rock, said mixture comprising a water-soluble thickening agent in the form of cellulose ether powder in an amount of 40-75% by mass, and hollow hermetic microspheres in an amount of 25-60% by mass. During active agitation, the dry mixture is diluted with water, in a ratio of 1 part per mass of dry mixture to 20-60 parts by mass of water, resulting in the stated relative viscosity.
