Taschenbuch. Condition: 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. Condition: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The monograph is dedicated to the issues of ore quality management in the open-pit mining of mineral deposits. It examines the theoretical foundations of ore stream quality formation, factors affecting the stability of ore quality indicators at all stages of extraction, and modern methods for monitoring, regulating, and managing the quality of mineral raw materials. Special attention is given to the influence of ore quality on enrichment and metallurgical processing, the application of probabilistic and statistical methods for assessing quality variability, and the analysis of geological, technological, organizational-technical, and economic factors that determine the effectiveness of ore stream management. The book presents criteria for assessing the quality of ore reserves, the principles and stages of ore quality management during mining, and issues related to integrating quality management into the overall mining technology management system. A separate chapter is devoted to the practical experience of managing ore stream quality at the Muruntau open-pit mine, as well as methods for forming the ore stream during the combined development of natural and technogenic deposits. 100 pp. Englisch.…

Taschenbuch. Condition: 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.…
