State and prospects of scientific researches of hydromechanization of mining works
Abstract
Hydromechanization of mining operations was first applied in the 30s of the last century during the development of gold-bearing placers in the Ural Mountains by open-pit operations. Later, since 1852, hydromechanization began to be applied in similar conditions in California (USA), where this method became especially widespread. Hydromechanization of underground works began much later. The first hydro-mine in the USSR was built in 1939 in the Donetsk basin. A few years before that, experimental work was carried out in coal mines in the Kizelov basin in the Urals and manganese mines in the Nikopol region. At present, hydromechanization is widely used in open-pit mining for various purposes and in the development of coal deposits by underground works.
