Abstract
Theoretical substantiation and results of experimental studies of the action of charges with axial cavity in boreholes are given, the mechanism of gas cumulative jet impact on rocks is described. Industrial tests of charges with axial cavity at quarries have shown the possibility of overburden reduction by 30-40%.
