Implementation of production potential of high-performance equipment— A key trend of improvement in underground mining of power-generating coal

The Russian and international coal market conditions are analyzed. The challenges of power-generating coal mines are specified. The competitive recoverability of coal mines with enhanced-performance, modern, reliable and high-production equipment is illustrated. The implementation philosophy of the coal mine production potential is formulated. The performance evaluation procedure is proposed and implemented in terms of cutting–loading equipment of Russia’s top coal mines (Yalevsky mine). The main causes of high-production equipment downtimes in mines are analyzed. The reasons of mis-implementation of production potential of modern high-production coal mining equipment are revealed, and the top-priority trends of improvement and efficiency enhancement in underground coal mining are identified. The implementation of the production potential of coal mines requires fulfillment of certain conditions, namely, availability of highly workable reserves and advanced coal mining technologies, compliance of the technologies with geological and geotechnical conditions variable in time and in space within the mining lease limits. The further research aims at structural and parametric optimization of process flows in high-rate mining of flat-pitching gas-bearing coal seams.

Keywords: underground mining, coal seams, longwalls, equipment, technical and economic performance, downtime, productivity.
