Technical and Practical Aspects of Application of Electro-Hydraulic Method of Rock Breaking in Polish Mining Industry

摘要

The steady demand for rock materials leads not only to on increase in mining but also to the need for decreasing the loss of material in the process of exploitation as well. It brings about an increase in use of explosives in opencasts and as a result an increase of after blasting gases volume, vibrations, the scattering (dispersion) of stone etc. All these factors affecting the environment lead to the research work for applying the electrohydrodynamic methods both in opencasts and underground mines. In the article the authors describe the concept of this method and construction of equipment which have recently been successfully introduced in mining, the results obtained determine the possibilities of using this method and the future directions. The results of combined method with high-pressure water jet cutting are also described.
