Abstract

A considerable amount of small-scale ore deposits of precious metals has been explored in the Far East. Many of them are characterized by advantageous small depth of ore bodies and relatively high content of metal in the ore. Therefore, the purpose of the article is creation of an excavation complex for the development of steeply dipping ore bodies of moderate thickness. The article analyzes the well-known technical devices and mineral excavation methods that decrease the volumes of overburden operations under the development of deposits. Modern mining machines are equipped with milling tools allow to carry out the excavation of solid rocks without their prior weakening or loosening by drilling and blasting. The author proposes a technology for developing steeply dipping ore bodies of moderate thickness using an excavation complex and crawler dumps to perform mining in remote areas where the construction of roads and delivery of various mining equipment for mining by traditional technologies are often not economically feasible. The excavation complex is mounted on a crawler chassis and is equipped with dozer equipment, a telescopic boom with a milling working body and a bucket loading equipment for lifting the milled rock mass from the mine face to the daylight surface. The movement of the milling working body in the bottom is carried out by means of a telescopic tip that is pivotally attached to the telescopic boom sliding section. The mining technology of small-scale steeply dipping ore bodies with the use of the proposed excavation complex allows to reduce the number of mining equipment and production overburden removal.
