These ways are based on usage of power and temporary parameters of and legitimacses of a rock pressure manifestation in face zone of a development. Usage rhem has allwed to lower apecsfic consumption of exploves, to lower a volume of drilligs, to increase a heading advance per round to shotholes length ratio, to reduce destruction of soils behind desigh section(cross-section) of a development and to pick up speed of realization of mine workings. The guidelines and technological blasting patterns for a drivage in condition of the tight mining massif are designed Product Description popup.authors popup.nrat_date 2020-04-03 Close
