Zusammenfassung: | The invention relates to the technical field of metal mine mining, and particularly discloses a continuous mining method suitable for micro-inclined medium-thick to thick ore bodies, which comprises the following steps: stoping the ore bodies in sections and steps to reduce ore loss caused by reserving ore pillars; wherein the chambers in the first step adopt trackless process bottom structures of trenches, ore removal access roads and mining preparation main lines, and the mining preparation main lines utilize mining preparation roadways at the bottoms of the chambers in the second step; the chambers in the second step are stoped after all the chambers in the first step are stoped and cemented and filled, and the chambers in the second step are of a bottom structure of a trackless process including a trench, an inclined chute, an ore removal access road and a mining preparation main line. According to the method, the mode that a roadway is excavated in a filling body in a traditional mode is eliminated, the |
