Моделирование и управление параметрами поточных технологий с локальным гидротранспортом и обезвоживанием угля на основе анализа структуры проходческого цикла

Abstract

Introduction. The article discusses the issues of modeling various variants of flow line tunneling technologies based on an analysis of the structure of the tunneling cycle. Materials and methods. As research methods, the authors used: analysis of the structures of the tunneling cycle of continuous mining technologies, mathematical modeling of processes and operations, and industrial testing of options for implementing the proposed technological tunneling systems. Results. The results obtained during the implementation of the economic and mathematical model for the variant of the flow technology presented above showed that the following parameters of the technological scheme are optimal: technical productivity of the combine – 1.1 m3/min; process water consumption – 200 m3/h; number of drilling rigs – 2; the number of miner units is 6. The speed of development with these parameters of the flow technological scheme will be 880 m3/month, the labor productivity of miners is 14.8 m3/person during the work shift. Conclusion. The article summarizes the results of research on the development, justification of parameters and implementation of various options for in-line technologies for carrying out inclined workings with a hydraulic slope for various purposes for a wide range of conditions of their application. Resume. Implementation of the model proposed by the authors made it possible to determine the primary area of application of the considered version of the flow technology for carrying out preparatory workings in relation to the mining and geological conditions of the Kuzbass mines. Variants of the considered technological schemes for carrying out workings were implemented during the mining of reserves of the Anzherskaya-Yuzhnaya-3 mine, during the underground mining of reserves of the Listvyansky and Kedrovsky open-pit mines located in the Kemerovo region of the Russian Federation and the implementation of a project for the combined mining of a graphite deposit in middle Vietnam.Suggestions for practical application and direction for future research. The materials of the article may be useful for scientific and design organizations, coal mining enterprises in modeling and implementing precision mining technologies.
