Background

In the underground production process of the mine, the corresponding mining method is required to complete mining and ore removal tasks. The existing mining methods comprise a ore-sliding method and a stage caving method, the two methods are very widely applied to mine production, a plurality of mines are mined by the two mining methods, and the two mining methods bring huge economic benefits to the mines. Corresponding scraper path engineering is required to be constructed in the two mining methods to complete the ore removal task of a stope. However, the existing scraper path engineering can not turn, so that the ore body with the changed ore body trend can not be removed by the existing scraper path engineering. This has caused many mines to divide into two stopes for a stope, has brought huge potential safety hazard and huge waste for the exploitation of mine. Because the minimum 3 meters of mine wall must be reserved between two stopes, if the control is not good in the mining process, the mine wall can be accidentally run through or inclined slope occurs, so that safety accidents are caused, a new mine underground double-rake-way ore removal structure is needed to be developed, and the problem that the scraper track engineering can not turn is solved.
