Embodiment 1

[0029] like figure 2 and figure 1 As shown, the upper stage piercing vein 18 and the lower stage piercing vein 7 are arranged in the center of the panel. The upper stage piercing vein 18 communicates with the ventilation filling shaft 15 in each mine room or inter-column through the ventilation filling shaft connection road 16, and the lower stage piercing Vein 7 communicates with pedestrian water filtration patio 12 in each mine house or inter-column through pedestrian water filtration patio connecting road 11. The panel centralized chute 4 is arranged outside the vein, the panel centralized chute 4 communicates with the upper stage piercing vein 18 and the lower stage piercing vein 7, the panel centralized chute 4 communicates with each chute connecting road 5, and each chute connecting road 5 communicates with the Respectively corresponding subsection level lanes 8 are connected.

[0030] Mechanized mining is adopted, the mining room is recovered first, and then the inte...

Embodiment 2

[0040] The total number of mine rooms and inter-columns arranged at intervals is 5 to 6, and the width of mine rooms and inter-columns is b Both are 12~15m, and the layered height of mine room and inter-column h Both are 6~8m.

[0041] Described filling material 13 is respectively: when mining house mining, use high-strength filling material 13 to fill, and the lime-sand ratio of high-strength filling material 13 is 1: (8 ~ 10); Filling material 13 is used for filling, and the gray-sand ratio of medium-strength filling material 13 is 1: (12~15).

[0042]The slope β of the external ramp 2 is 15-18%.

[0043] The slope α of the stope connecting road 9 is 16-18%.

[0044] The height c of the top column 17 and the bottom column 10 are both 6-8m.

[0045] The beneficial effect that this specific embodiment has compared with prior art is:

[0046] ①Large production capacity

[0047] In this specific implementation mode, the production of the ore body in the stage is organized ...

Abstract

The invention relates to a panel mechanized centralized ore-pass upward horizontal cut-and-filling stoping method. According to the technical scheme, an ore body is divided into panels in stages along the trend, and the panels are divided into chambers and studs at equal intervals according to the trend; a top pillar (17) and a bottom pillar (10) are left; the chambers and the studs are horizontally layered; a sublevel roadway (8), a pulse external slope ramp (2), a stope cross gateway (9) and a panel centralized ore-pass (4) are distributed on the panel lower plate to form a trackless stope preparation system; an upper-stage transverse drift (18) and a lower-stage transverse drift (7) pass through corresponding ventilation filling shaft cross gateway (16) and pedestrian water-filtration patio cross gateway (11) to be communicated with a ventilation filling shaft (15) and a pedestrian water-filtration patio (12) in each chamber or ore pillar. Mechanical mining is adopted, so that all chambers are stoped at the same time, and a mined-out area and the stope cross gateway (9) are filled when every layer is stoped; after the chamber mining is completed, the studs are stoped by using the same method, and the top pillar (17) and the bottom pillar (10) are finally stoped. The panel mechanization-centralized ore-pass upward horizontal cut-and-filling stoping method disclosed by the invention has the advantages of being high in production capability, high in stoping efficiency, simple in stoping process and good in operation safety.

Description

technical field [0001] The invention relates to a filling mining method. Specifically, it relates to a panel mechanized centralized chute upward horizontal layered filling mining method. technical background [0002] The filling mining method is a green and environment-friendly mining method, which can immediately fill the goaf and effectively reduce the impact of mining on the mining environment. At present, thick and large ore bodies are generally mined by two types of mining methods, the open-field method and the caving method. Method Mining will cause a large area of ​​surface subsidence in the near or long term, and the subsidence will pose a serious threat to the environment of the mining area and the safety of industrial and agricultural production in the mining area. [0003] As the country pays more and more attention to the environment and safety of mining areas, it is a development trend that the filling mining method replaces the open field method and the cavin...
