Automated determination of rock crushing zones in the collapse

Purpose. Development of an automated method for determining the zones rock crushing in collapse order to select rational technologies drilling and blasting operations. Methods. Methods positions nodal internal points coordinate grid blasted collapse, approximation methods, matrix theory, numerical methods technology are used. Findings. An is described. It based on analytical granulometric composition rocks active passive crushing. The meth-od correlates granular mass with blockiness mass, physical mechanical properties rocks, chemical characteristics explosive used, parameters charge location mass. Originality. Based joint application calculation block, sizes was developed first time mining.Based mining. Practical implications. On basis method, a computer program created determination block. With help this program, small, medium large block can be quickly fairly accurately determined under various conditions masses. Locations thus established serve as tool choosing drilling, blasting, excavating loading operations, which determines their practical value.
