Paperback. Condición: new. Paperback. The monograph presents the results of scientific research aimed at increasing the efficiency of drilling and blasting operations by extending the duration of explosive impact on rock masses. The main focus is on improving the design of borehole explosive charges and optimizing stemming parameters. The physical processes of interaction between detonation products and stemming material, as well as the patterns of stemming movement in the borehole, taking into account external factors, are considered. Mathematical models for predicting the granulometric composition of rock fragmentation products have been developed. New technological solutions have been proposed that ensure improved fragmentation quality and drilling and blasting efficiency. The monograph is intended for researchers, practicing engineers, doctoral students, applicants, master's students, and students of mining specialties engaged in improving blasting technologies and increasing the efficiency of rock fragmentation. This item is printed on demand. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The monograph considers the scientific and practical foundations for ensuring the stability of the sides of deep open pits during drilling and blasting operations. A comprehensive analysis of theoretical research and industrial experience of open pit mining of mineral deposits, aimed at establishing the rational parameters of the sides and ledges of open pits is carried out. Particular attention is paid to the study of physical and mechanical properties of rocks forming the instrument massif, as well as the assessment of their influence on the stability of slopes.The results of physical and mathematical modeling of seismic impact of explosions of dispersed borehole explosive charges are presented. On the basis of the obtained theoretical and experimental results the effective methods of rock mass state control are proposed to ensure the stability of the sides of deep quarries. The schemes of orientation of rows of boreholes at mass explosions, and also seismic safe way of blasting operations in the near-contour zone of a quarry are developed. The technology of scarp slope formation on the limiting contour of the quarry with the use of inclined contour boreholes is proposed. 104 pp. Englisch.

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The monograph examines the theoretical and practical aspects of conducting drilling and blasting operations during open-pit mining in water-logged rock mass conditions. The mechanisms of rock destruction by explosion in a water-saturated environment and the influence of hydrogeological factors-water content, pore pressure, and filtration processes-on blasting efficiency and pit slope stability are analyzed.On the basis of a complex of theoretical studies, laboratory experiments, and engineering-geological observations, the features of the stress-strain state of water-saturated rocks under explosive impact were identified. Zoning of the quarry field was performed according to the degree of water content, which allowed for the substantiation of rational parameters of drilling and blasting operations for various conditions. Technological solutions have been developed for working in water-filled boreholes, including charge designs using absorbent materials and hydrogels. The results of industrial tests confirmed a reduction in explosive consumption, a decrease in charge failures, and an increase in the economic efficiency of operations.
