MODELING OF CUTTER-LOADER CONTROL IN HIGH PRODUCTION LONGWALLS

Modern coal mines are equipped with all mechanical means required for road making and coal cutting. The average daily face output has grown considerably. Therefore, appropriate gas and dust conditions, as well as reliable degassing and ventilation modes are needed. The problems +connected with the coal industry development should be solved using the best advanced technologies aimed to ensure economic effect and, first of all, improved working environment and safety of miners. The topical questions of improvement of mechanized longwall equipment efficiency at the expense of operational control are discussed. The modeling results demonstrate necessity and efficiency of operational control over cutter–loaders in highly production longwalls. The developed model of coal breaking and haulage within a longwall makes it possible to optimize control modes of cutter–loader advance speed and to ensure safe and efficient coal mining. Given certain conditions, coal cutting is possible without full-time presence of miners in the face area. Modeling of operational control of mechanized high-production longwall equipment in terms of Polysaevskaya Mine of SUEK-Kuzbass has proved feasibility of improvement of longwall equipment efficiency.
