Inclined layered solid ore deposit mining method

Abstract

The invention belongs to the technical field of ore deposit mining, and discloses an inclined layered solid ore deposit mining method. The inclined layered solid ore deposit mining method comprises the following steps of that an inclined ore body is divided into ore blocks along the trend of the inclined ore body, and an air return way, a transportation way and a pseudo down-dip working surface are arranged; a mining machine is used for mining on the pseudo down-dip working face, and advancing is carried out in the trend of the inclined ore body; after ore breaking, ore is automatically loaded into a scraper conveyor to be conveyed to the transportation way, crushed by a crusher, transferred by a reversed loader and conveyed to the ground by a belt conveyor; after mining is completed, a working face support is moved and supported in sequence; and a goaf adopts a natural caving method to manage a roof. The mining method is reasonable in design and simple in process, and continuous mining and continuous transportation are achieved along a ore deposit; the inclined layered solid ore deposit mining method can effectively solve the problems of large pillar ore quantity loss and dilution, low recovery rate, complex process and the like in the existing inclined layered non-coal solid deposit mining; the inclined layered solid ore deposit method is suitable for a non-coal solid ore deposit with the dip angle of 35-65 degrees and the thickness of 0.8-5 m.

Description

technical field [0001] The invention belongs to the technical field of ore deposit mining, and relates to a mechanized mining method for a solid ore bed, in particular to a method for mining an inclined layered solid ore bed. Background technique [0002] Mining of non-coal solid deposits is an important part of the mining industry, and its mining targets are all metal and non-metal deposits except coal, oil and natural gas. The mining method of non-coal solid deposits, although some domestic mining is still dominated by open-pit mining, but with the development of industry and science and technology, the demand for mineral raw materials has increased rapidly, many open-pit mines have been converted to underground mining, long-term underground mining The mines are also gradually into the deep mining. Non-coal solid deposits with a dip angle of 35°-65° and a thickness of 0.8-5m are generally mined by the open-field mining method. If the top, bottom and inter-pillars are ins...
