Abstract
It is found that the increased radiation exposure of rocks treated by accelerated electrons changes the rock deformation and strength characteristics: ultimate compression strength as well as moduli of deformation and elasticity. The uniaxial compression strength of granite is 68.33 MPa without treatment and 35.08 MPa at the absorbed radiation dose of 10 kGy. The established possibility of weakening of rocks by accelerated electrons can be used to reduce consumption of electricity during ore pretreatment and to minimize loss of useful components in processing.
