Specifics of the use of excavation areas of large size with intensive mining of flat coal seams

The influence of various factors of technology and development systems on the reduction of energy consumption during underground mining of coal seams is considered. Examples of best coal mining practices in leading coal mining countries are given. The technological schemes are shown that ensure the full use of the potential of high-performance equipment of mechanized purification complexes. The task was to substantiate the technical possibility of increasing the length of the lava number 5003 of the mine named after V.D. Yalevo JSC "SUEK-Kuzbass". The main trends of energy saving and increasing the load on the working face during the development of coal seams with long pillars are identified.
