It has been established, that to the present time with the purpose of primary destruction the know-how of blasting with applying of blasthole charges from explosives of local cooking reshaped in sleeves, which have diameter, smaller than well bore is more justified. Are justified: the rational sizes of air and water backlashes along walls of wells. Dynamics of immersion of charges in sleeves in wells without water and with water in details studied. The explosive structures for loading wells, technological operations and means of opening-up of sleeves, charges and their loading has been designed. Has been analytically justified rational thermodynamic and knock ratings of he explosive structures for primary and secondary destruction. Achievement of efficiency of secondary destruction with applying of mudcaps has been justified experimentally. Most rational of known poorly dense free-flowing explosive structures has been designed. They are ecological secure, cheap and effective in applying at destruction by mud caps of oversized fractions of mined ro ck on opencasts.
