MIXTURE TO PRODUCE SUSPENSION OF TRANSMITTER AND SYMPATHETIC DETONATION REDUCER PULSE IN THE HOLE, AND METHOD FOR SUSPENSION PRODUCTION

摘要

The invention relates to production of large-block stone from rocks in pits with use of drill-blast operations. A mixture for preparation of suspension of transmitter and damper of detonation pulse of blast in blast hole, as such non-explosion substance is used, with possibility of placement between the fuses with explosive substance with high rater of detonation and walls of drilled at boundaries of block of rock blast holes that includes a powder of cellulose ether as water-soluble thickener in amount of from 40 to 75 % by weight and hollow hermetic micro-spheres in amount of from 25 to 60 % by weight. At active agitation one dilutes with water dry mix at ratio 1 part by weight of dry mix per 20-60 parts by weight of water, with achieving given conventional viscosity. The invention makes it possible to produce high-grade block stone of rocks without damage of blocks with minimal expenses of explosive material and minimal harmful effect on ecology.
