| description | The invention provides a continuous mining method suitable for a high-middle section. The method comprises the steps of S1, a stope preparation project and S2, a back production project. The stope preparation project comprises the steps that S101, a high-middle section stope is divided into a plurality of layered stopes; S102, an out-of-vein roadway is tunneled along the trend on the lower plate of the ore body, and then a sectional flat roadway and a stope connected roadway are tunneled, wherein the central line of the stope connected roadway is perpendicular to the central line of the corresponding layered stope; S103, a filling return air service raise is arranged and communicates with the out-of-vein roadway, the sectional flat roadway and the stope connected roadway; a waste stone chute and an ore chute are respectively arranged; and S104, a bottom pillar is not left in the high-middle section stope, a bottom-pulling roadway is directly tunneled at the upper part of a bottom plate, the bottom-pulling roa |
