High-dipping medium thick ore body mining method

The invention discloses a high-dipping medium thick ore body mining method. Filling is executed in an upward horizontal segmental manner. A middle section of an ore body is divided into five segmental flat alleys (1) according to a vertical height direction; a steel wire rope and a pipe seam anchoring rod are arranged in a goaf of a first segmental flat alley (1-1) of the middle section; a paste body, which is formed by adding cement into concrete C25 or tailings and serves as a cemented filling body (4), is used for filling the goaf; dry-type filling bodies (3) are filled in second, third, fourth and fifth segmental flat alleys (1-2, 1-3, 1-4 and 1-5) of the middle section; a studding (5) reserved in a mining field is replaced by an artificial rubble concrete supporting column (6). The high-dipping medium thick ore body mining method is simple in construction, and can be used for effectively improving the ore recovery rate and the safety and reliability of a mining field.
