Résumé :

Sebuku is occupied by serpentinized ultramafic (peridotite) rocks, gabbro, and chert which are ophiolite series formed in the oceanic crust, in the middle occupied by tuff and claystones. The purpose of this study was to determine the distribution pattern of iron ore deposits. The research area illustrates that the distribution of Fe elements with high levels of >48% is concentrated in the northeast-southwest part, while Fe elements with levels of <48% are concentrated in the southwest-northwest part of the west.

Résumé :

Explosive destruction of the rock formation is substantiated by several theories developed by well-known scientists. The improvement of quality of preparation of rock mass to excavation, by an excavator without an increase in the value of specific consumption of explosives is important in the present time. Traditionally, to increase the impact time of detonation products on the rock hard tamping was used. The problem is in the rational redistribution of the explosion energy due to the use of a borehole charge, and in particular, in the tamping of low-density, porous materials. The more intensi
