The development of ideas for improving explosive destruction of rock masses – the basis of progress in mining

Article preview

The article describes the main areas of research in the field of the explosive destruction of rocks used in mining. The results of studies carried out in recent years are presented. Information on possi-ble applications for breaking up rocks of various energy sources is provided. Ideas are given on the possibility of raising the efficiency of explosives for mining rock by increasing the scale of the ex-plosive destruction. Information about the widespread adoption of these methods at Russia’s biggest iron ore companies is presented. Recent results on the fracture processes at different levels of scale up to destruction to form particles of submicron size are shown. Studying the structural transforma-tions of rock mass at the micro and macro features of allocation and distribution of energy in the charges of various designs allowed us to control the action of a new explosion by breaking up rock masses and the complex structure of multicomponent fields.

Physical-technical bases and new technologies of high ledge destruction by large-scale explosions

Article preview

The paper presents a theoretical analysis of highwall destruction by blasting. Peculiarities of blasting in high faces at open-pit mining operations in Russia are analyzed. New approaches to drilling processes in high faces are proposed. Possibilities of application of walking machines for downward digging (walking excavators) are described.

On approaches to determining blast efficiency in geotechnology

Article preview

As is known, the external indicators of the development of mineral deposits (geology, requirements for the final technological indicators, etc.) are constantly becoming more complex. At the same time, in the modern mining practice the most important role is played by the processes of destruction as the basis of mining, and the main means at the head of all geotechnologies of solid minerals extraction is the explosive energy. It has a price and its intrinsic controllability.
