New solutions for mine transport for the transition to in-line mining of minerals

Mining transport systems largely determine effectiveness of mining enterprises. The study aim is developing new technical solutions for progressive mining transport systems based on the harmonization of technological solutions and equipment. The aim is achieved through the introduction of new mine transport designs compatible with tunneling machinery, enabling change from cyclic concept of a mining enterprise activity to in-line system concept. The option is considered on development of designs of steeply inclined and curving conveyors in transport workings, including overhead and floor pipe belt conveyors and airdraulic pipeline systems for delivering lump ore from the face to the surface in the mine. At the same time, the basis of the proposed technology and equipment is the method of contactless hard rock breaking by using hydroimpulsive facilities. The proposed solutions allow decreasing mineral mining and processing capital and operating costs.
