Abstract

The invention provides a mechanical mining method for a first mining layer of a broken ore body, and relates to the technical field of mining, the mechanical mining method for the first mining layer of the broken ore body comprises the steps that a plurality of panels are divided in the first mining layer, and each panel comprises an in-vein connection way, an in-vein accurate mining drift and a plurality of first stoping drift; an included angle is formed between each of the in-pulse accurate mining drift and the first stoping drift and the in-pulse connection way, and the in-pulse accurate mining drift and the first stoping drift are arranged in parallel; and performing advanced pre-support on the intra-pulse connection way and the intra-pulse accurate mining drift, performing advanced pre-support on each first stoping drift through the intra-pulse connection way and / or the intra-pulse accurate mining drift, performing mechanical stoping operation under the advanced pre-support, and performing filling after stoping is completed. According to the mechanical mining method for the first mining layer of the broken ore body, the problem of mechanical continuous mining of the first mining layer of the broken ore body can be solved, and the long-distance, continuous and efficient mining advantages of mechanical continuous mining are exerted.
