Determination of rational parameters of foam plastic elements for creation of air spaces of borehole charges

Article preview

The possibility of elements from a foam plastics use for creation of air gaps deep-hole charge is analyzed. The requests to elements used in various types of slits are formulated. Is revealed, that the elements of the cubic form are most universal and approach for shaping air gaps in any types of slits.

Ways to increase the time of blast action on the massif

Article preview

The complex of measures for increasing the time of explosion impact on the rock mass is analyzed. The results of experimental explosions with different types of boreholes are given. It is revealed that the use of a special locking baffle together with the formation of air gaps inside the charge and under the baffle improves the quality of crushing with a simultaneous reduction in the consumption of explosives.

Damping plate parts test of the moving cover

Article preview

At the 1st International Scientific Conference on Physical Problems of Rock Fracture we presented the results of scientific and technological substantiation of progressive technology of open-pit mining based on a fundamentally new approach to drilling and blasting operations: rock fracturing is carried out by layer-by-layer (from top to bottom) blasting of horizontal borehole charges of reduced diameter (with preliminary slotting along the contour of the blasted volume) under a mobile shelter in the form of a shield with damping elements.
