Embodiment 1
[0022] A medium-thick and gently inclined broken ore body upward layered filling mining method, comprising the following steps:
[0023] (a) Divide the ore block into several mining panels, and arrange ramps 7 on the hanging wall of the ore body. The ramps 7 are connected to the ore crossing roadways 6 in each segment. The ramps 7 are used for scrapers and personnel. walkway;
[0024] (b) Divide each stope into five sections, namely the first section, the second section, the third section, the fourth section and the fifth section, and each section is connected by a ramp 7;
[0025] (c) Arrange layered drifts 10 hanging on the roof of the ore body in the stope of each section as the passage of the scraper for ore output in the vein, and arrange sub-level roadways outside the upper plate veins of the second to fifth sections. Segmental conveying headway 8, segmented conveying headway 8 is parallel to the ore body trend;
[0026] (d) An ore delivery chute 5 is arranged on the h...
