specific Embodiment approach
[0017] The layered and segmented combined mining method of the broken ore body interlayer of the present invention, its preferred embodiment is:
[0018] The layered and segmented combined mining method of the broken ore body interlayer comprises steps:
[0019] A. Along the trend of the broken ore body interlayer, the panel area and the inter-panel column are sequentially divided, and the vertical direction in each panel area is successively divided into a one-step mine stope and a two-step mine pillar stope. The one-step mine stope includes Broken ore body interlayer mining, the two-step ore pillar stope includes the stable ore body mining on both sides of the broken ore body interlayer;
[0020] B. The horizontal direction of the mine stope in the first step is composed of two parallel approaches, and the number of approaches in the vertical direction is determined by the height of the section, and it is filled immediately after mining to form a filling replacement column; ...
