Myslitsky S. Development of methods of intensity and evenness increase of the explosive crushing of mountain breeds arrays of sectional and stratified structure

Intensity and evenness increase of the explosive crushing of mountain breeds arrays of the stratified and sectional structure is the purpose of work due to planning of rational parameters of the mining holes net and charts of charges connection. It is theoretically and experimentally well-proven that destruction of the stratified mountain breeds athwart to stratification increases intensity and evenness of their explosive crushing. The surface of layer destruction is formed athwart to its flat, if direction of the main squeezing tensions at the explosion to stratification makes a corner the size of which depends on correlation of scopes of breed durability at compression and tension. The method of evaluation of power parameters of mechanical effect at destruction of models from rocky mountain breeds is grounded and according to the results of research of samples remaining durability. It is shown that experimental determination of toughness reduction energy does not imply other methods parameters more difficult to determine. Basic outcomes of the work have been applied in quarries of the Kremenchuk region.
