Deeply lying natural resources decomposition method for mining industry, involves indirectly misplacing contour mine opening depending on decomposition of strip and recultivating mining compound to drive decomposition opening between strips

摘要

The method involves driving a decomposition opening (1) and a surface contour mine opening (2) at a boundary of a decomposition strip (A). A decomposition complex is assembled in the mine opening. A surface discharge and mine air section (4) is driven. The complex is converted after entering into the decomposition opening or in the mine opening. The mine opening is indirectly misplaced, during decomposing another decomposition strip (B), depending on the decomposition of the strip (B). A mining compound is recultivated to drive another decomposition opening between the strips.
