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 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...

Abstract

The invention discloses an upward horizontal stratification filling mining method for a medium thickness gently inclined broken ore body. The upward horizontal stratification filling mining method forthe medium thickness gently inclined broken ore body comprises the following steps that (a) an ore block is divided into a plurality of mining wall areas, and an inclined roadway is arranged in a hanging wall of the ore body; (b) each stope is divided into five segments which are a first segment, a second segment, a third segment, a fourth segment and a fifth segment correspondingly; (c) ore bodyhanging roof stratification drift ways (10) are arranged in the stopes of the segments; (d) an ore removal draft shaft (5) is arranged on the hanging wall of the ore body; (e) the mining of the wholewall area is divided into two steps for mining; (f) the mining of the first segment is carried out; (g) after the mining and filling of the first segment are completed, the mining of a second stratification is carried out; (h) carry-scrapers enter the stopes from inclined roadways (7) and ore removal transverse roadways (6); and (i) a mining process of the third segment, the fourth segment and the fifth segment is the same as the second segment.

Description

technical field [0001] The invention relates to the technical field of underground mining methods for metal ore deposits, in particular to an upward and horizontal layered filling mining method for medium-thick, gently inclined broken ore bodies. Background technique [0002] The mining of gently inclined and broken ore bodies has always been a difficult problem in underground mining methods. A safe and effective mining method has not been found. In addition, the ore body is broken, which further increases the difficulty of ore body recovery. 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 The body mining effect is not good. Contents of the invention [0003] In view of the above-mentioned problems, the p...
