Formation and transformation stages of computer science and computer technologies department of mining institute are considered. The characteristic of educational and research work at the department and its contribution to the task of efficiency increasing of mining production is showed. The tasks of department at the present stage are defined.
The article presents research work of the Informatics and Computer Technologies Department on the application of modern computer technologies for teaching and testing systems. Two research works are described: a universal system of computer testing and a system for assessing the quality of articulation of Russian digits. The universal system of computer testing is developed on the basis of new information technologies, testing records and testing itself. The testing system is oriented to a wide range of uses, including knowledge control in the learning process and test taking. The system for assessing the quality of articulation of the ten Russian digits is based on modern advances in speech technology and allows you to evaluate both the overall quality of articulation and pronunciation errors of word length. An experimental study of the system allowed us to conclude that the assessment it produces corresponds to the experts' assessment in about 73% of cases.
The issues of assessment of technological efficiency of bauxite raw material stabilization in terms of processing processes are considered here for the conditions of PO Sevuralboksitruda (SUBR) and Bogoslovsk Aluminium Plant (BAP).
The effectiveness of ore quality management systems at mining and metallurgical enterprises is largely determined by the structure and parameters of the organization of averaging characteristics of the raw material flow.
При обработке опытных данных существенное значение имеет проблема выявления и исключения резко отклоняющихся результатов наблюдений. Этому вопросу посвящены работы многих авторов, предлагающих различные критерии (статистики) для оценки резко отклоняющихся результатов. Однако, как отмечают Э. Гумбель и Ю. В. Линник, большинство авторов ограничиваются случаем нормального распределения результатов наблюдений ...
Features of distribution of chemical elements in rocks are considered as a geochemical criterion in the study of magmatic and sedimentary complexes of rocks and their relationship with minerals. As it is known, geochemical studies increase the depth of search for mineral deposits. These searches are based on the study of the regularity of distribution of chemical elements in rock strata. Consequently, for geochemical prospecting it is important to simultaneously determine many chemical elements and their quantitative ratio in various rocks of separate regions, sites and zones of the investigated territory. In this case, a large number of samples are investigated. It can be hundreds, thousands and tens of thousands of analyses. The main volume of analysis is made up of rocks and loose sediments. Minerals and ores in this case represent a smaller number of determinations, but their performance can be specific ...
