3. Blasted breaking operating of the stressed state rock massif. To develop the method of operating the blasted breaking using extending stemming. Methods of research are the methods of mathematical physics, physical modeling and investigating high-speed processes using equipment for measure tensions and time intervals. The dependence of the detonation product's blocking time upon quantitative composition stemming's components was established. New method of control blasted breaking of the rocks on basis using the stemming PTC-1 with accounting the stressed state of the rock massif was developed. The adoptions of new method made it possible to reduce blasting costs and amount dust and toxic fumes in working's atmosphere and to receive economic effect 88 thousand grn. Sphere of employment is mining and coal industry.
