Amount of explosive destruction zones for cracked rocks with different crack filler for example Mikhailovsky GOK

Article preview

Present at the Mikhailovsky GOK, as in most such enterprises, the problem of oversize output entails additional time and material costs of preparing the rock for  processing. Calculation of fracture zones to reach their contacts will give an  opportunity to improve the efficiency of blasting. In this paper we consider the size dependence of fracture zones of fractured rocks from the characteristics of stress waves. Changing characteristics, in  turn, caused the value of  the crack opening and characteristics of matter, they are filled. The calculation of fracture zones  for ferruginous quartzite. Received the recommended dimensions of the grid of wells, depending on the type of crack filler.
