Downward layered up-down staggered drift filling mining method

Abstract

The invention relates to a downward layered up-down staggered drift filling mining method. The downward layered up-down staggered drift filling mining method is realized through stope arrangement, mining preparation cutting, stoping, stope ventilation and stope filling, and comprises the following steps that firstly, a preparation layer is formed at the top of an ore body, a first layered drift is started to be stoped after the preparation layer drift is completely filled, a second layered drift is stoped after the first layered drift is completely filled, and after the second-layer drift is mined, a downward layered up-down staggered drift stope structure is formed; the next-layer drift and the previous-layer drift are staggered up and down by 3 m and are stoped at intervals, the distance is 5 m, the top of the drift is a filling body false top, the upper half parts of the two sides are filling bodies, the lower half parts are ore bodies, and the safety is high; the two sides of the access are not prone to caving, and stoping is safe and reliable; the access section is large, and the production capacity is high; the inlet road is stoped along the top plate of the upper layer, the stoping direction is easy to control, and the engineering quality is high; the stope production organization is simple; the stope is simple in structure, the accurate mining project is simple, and the accurate mining project amount is small; large trackless equipment can be used in the stope, so that the production efficiency of the stope is greatly improved; and the stope filling engineering system is simple.

Description

technical field [0001] The invention relates to the technical field of mining in non-ferrous mines, and specifically refers to a filling mining method with downward, layered, up and down staggered approaches. Background technique [0002] The downward layered horizontal approach cemented filling mining method is a mature mining method. The ore body mined is thick, unstable and broken. It has high recovery rate, low dilution rate and good safety. With the characteristics of high degree of mechanization and large production capacity, it is widely used in non-ferrous underground mines in my country. [0003] 1. Mining and cutting: the middle section is vertically divided into sections, and the sections are vertically divided into horizontal layers, and mining is performed from top to bottom. Mining works are arranged on the hanging wall or footwall of the ore body, and the main mining works include mining slopes, section roads, layered connecting roads, slip shafts, filling ret...

AI Technical Summary

Problems solved by technology

[0012] (1) The production organization of the panel is complicated, and the requirements for the mining route are high

[0013] (2) The route section is small and the production efficiency is low

[0014] (3) The two gangs on the road are easy to help, which is not good for safe production

[0015] (4) Large amount of quasi-projects

[0016] (5) Not suitable for mining of small and medium broken ore bodies
