Experimental mining of three coal seams by transportless technology

In conditions of market economy and competition it is great importance to reduce the cost coal mining. It especially important when mining at complicated deposits Kuzbass. these choose technology stripping winning works, providing a minimum for them. There are two essential factors achieving this goal: reduction expenses on transportation overburden connected with alienation lands external dumps their reclamation. Therefore, promising technologies those that ensure placement maximum amount in internal dump. This condition sets task expanding scope boundaries application transportless technology, which used Kuzbass both independently combination transport technology. particular, combined Chernigovets open pit mine, where upper part quarry field, containing Kemerovsky seam, mined using The lower up 70 m high, includes three flat seams: Volkovsky, Podvolkovsky I, II, an experimental basis by (the volume works 5-10 % total volume). A distinctive feature experiment performance operations single dragline excavator, eliminates maintaining rope shovel bulldozer. experience practical interest other pits basin, as well any quarries similar geological conditions.
