Problems solved by technology

Traditional mining methods include room-and-pillar mining method, filling mining method, full-scale mining method and other mining methods. These mining methods have better mining effects for thin and extremely thin gently inclined stable ore bodies, but for moderately thick and above gently inclined broken ore bodies Body mining is not effective

Embodiment Construction

[0022] see Figure 1-3 , the medium-thick gently inclined broken ore body is upward horizontal layered filling mining method, and the mining method is carried out according to the following steps:

[0023] (a) First, a ramp 7 is arranged on the upper wall of the ore body, and the ramp 7 is connected to the ore crossing 6 of each subsection, and the ramp 7 is the walking passage for scrapers and personnel;

[0024] (b) Divide each stope into five subsections, which are 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 the layered level roadway 10 on the roof of the hanging ore body inside the stope of each sub-section, as the scraper channel for ore discharge in the vein, and arrange the sub-sections outside the upper wall of the second sub-section to the fifth sub-section. Sectional transport level road 8, sectional transport level road 8 is parallel to the strike...

Abstract

The invention belongs to the technical field of metallic mineral deposit underground mining methods, and particularly relates to a medium-thickness gentle-dip broken ore body upward horizontal layering filling mining method. The method includes the steps that firstly, an ore block is divided into multiple mining panels, each panel is further internally divided into multiple stopes, and stoping of each whole panel is conducted in two steps; in the first step, the stoping stopes are arranged at intervals, and studs are reserved on the two sides of each stope; in each stope, a segment is divided every 10 m, after being completely stoped, the next segment is bonded and filled with cement tailings, and the previous segment is stoped; accurate mining engineering in each panel is conducted on an ore body hanging side, and in order to protect the safety of chamber stoping, a pointed column supporting goaf is reserved in the middle of each stope; shallow hole ore falling is adopted, and ores are discharged through a carry-scraper; and after chamber stoping and filling in the first step are finished, the stopes used in the second step are stoped, and the method for stoping the stopes used in the second step is the same as the method for stoping the stopes used in the first step. The method is suitable for mining a medium-thickness gentle-dip broken ore body and has the beneficial effects of being safe in stoping, low in ore dilution and the like.

Description

technical field [0001] The invention belongs to the technical field of underground mining methods for metal ore deposits, and in particular relates to an upward horizontal layered filling mining method for medium-thick and gently inclined broken ore bodies. Background technique [0002] The mining of gently inclined broken ore bodies has always been a difficult problem for underground mining methods, and no safe and effective mining methods have been found. Traditional mining methods include room-and-pillar mining method, filling mining method, comprehensive mining method and other mining methods. These mining methods have better mining effect on thin and extremely thin gently inclined and stable ore bodies, but for moderately thick or more gently inclined broken ore bodies. The body mining effect is not good. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of medium-thick gently inclined broken ore body in which the ore block i...
