On the organization of excavation and transportation equipment in the coal-bearing zones at open pit mines [PDF]
E3S Web of Conferences, 2021 One of the essential issues of the benches’ development procedure is the choice of the method of seam development in the complex structure: joint development of rock and coal seams in one complex face or their separate excavation in blocks of 50-100 m in
