Increasing the Efficiency of Developing a Coal Mine by Optimizing Technological Parameters in Difficult Mining and Geological Conditions

Abstract

Гидроразрыв угольного пласта в шахтных условиях как панацея решения газовых проблем шахт (основы разработки и внедрения)

Justification of the technological scheme parameters for the development of flooded deposits of construction sand

“…Shovel excavators with hydraulic drive in combination with road transport are increasingly used in mining industry in the development of mineral deposits of various types [14]. Shovel excavators with hydraulic drive are widely used in excavation and loading operations, especially when the supply of electricity to mining areas is difficult, as well as in pits of small and medium production capacity [15].…”
