STATE AND DIRECTIONS OF DEVELOPMENT OF THE RESEARCH PROGRAM TECHNOLOGIES OF UNDERGROUND COAL MINING

Abstract

The current state of underground coal mining technology in Russia and abroad is characterized by an increase in the load on mine faces and an increase in the pace of conducting preparatory workings. Between 2000 and 2014, Russia experienced a 16% increase in underground coal production. The daily load on the mechanized cleaning face (MCF) increased from 1,324 to 4,267 tons, i.e. by 3.2 times; the worker's productivity increased almost twofold. In some Kuzbass mines (Listvyazhnaya Mine LLC, Chernigovets Branch OJSC - Yuzhnaya Mine, SUEK OJSC Kuzbass») the average daily load on the KMZ is 9 ‒ 10 thousand tons, i.e. 2 ‒ 3 times higher than the average for the basin. However, many mines operate with a load of 0 ‒ 5 thousand tons per day. The main reason for the unstable operation of the KMZ mines in Kuzbass compared to the performance of high-performance domestic and foreign mines is the insufficient adaptability of modern Russian and imported technical equipment and technology.
