Optimalization of the transport of excavated material in hard coal mines based on improvements in the automatic control mode

Abstract

Hard coal mines are increasingly struggling with the widespread phenomenon of the decarbonization of the economies of European countries. As a result, they are forced to constantly look for opportunities to reduce unit mining costs. This is extremely difficult because producers of mining machinery and equipment are unwilling to incur high costs for the research and development of new products, as this industry is burdened with a high risk of unprofitability. This article describes one of the examples in which an attempt was made to reduce the costs of hard coal mining by modifying the method of controlling underground haulages consisting of belt conveyors in the Polish LW “Bogdanka” mine.
