Embodiment Construction

[0021] The present invention will be further described below in conjunction with the drawings.

[0022] The technical scheme of the mining method of the present invention is as follows:

[0023] 1. Divide the ore block into ore houses and pillars arranged at intervals along the direction of the ore body. The width of the ore houses and pillars is 10m; the production is organized with 6~8 groups of ore houses and pillars as the mining unit. Panel, continuous mining along the strike, such as figure 1 .

[0024] 2. The height of the middle section of the mining is 50m, and the mining is from bottom to top. The method of non-track mining outside the footwall vein is adopted. The technical points are as follows: Parallel to the boundary of the footwall of the ore body, segmented roadways 3 are arranged, and each segmented roadway 3 is connected to the out-of-vein slope road through the ramp connecting channel, and the stope is segmented Connecting lane 4 connects the stope with each sec...

Abstract

The invention discloses a layered top-controlling filling mining method for residual ores in a deep hole in a diskless area. An ore body is divided into ore room ore columns which are arranged at intervals along the travelling direction, and production is preformed by taking 6 to 8 ore room ore columns as a unit; a mountain outer oblique slope, a mountain outer sectional stulm, a sectional contact way and a mountain outer middle-section orepass form a mountain outer rail-free mining preparation system; after bursting and ore falling in medium and deep holes are performed in the ore room ore columns, a part of ores is shoveled out, and the other ores are temporarily left in a stope to form an ore pile of which the top is provided with a hollow top space with the diameter of 1.5 to 2m; a layer of mine body with the thickness of 2.0 to 2.5m is exploited from the ore pile, a 1/4 three-center arc top plate is formed by a control burst method, the out ores are pressed and exploited on the ore pile, and surrounding rocks are crushed on an anchoring rod or an anchoring net supporting and protecting top plate and a long anchoring rope supporting and protecting upper disc; the ores are taken out in a concentrating way after the top is protected, and cement and tailings are glued and filled to a 3.5-4m position; and the steps are repeated until ore blocks are completely stoped and the top is connected and filled. The method has the characteristics of safety, high efficiency, low barren loss, low cost and the like.

Description

[0001] Technical field [0002] The invention belongs to the technical field of mining, and relates to a panelless area medium and deep hole ore retention layered top control subsequent filling mining method. This method is mainly suitable for the mining of metal ore bodies that are extremely thick and stable, and require large production capacity and high efficiency. technical background [0003] With the continuous progress and development of filling technology and trackless equipment, the mechanized horizontal filling mining method and the approach filling mining method have high ore recovery efficiency and small roof exposed area, which is especially suitable for the mining of unstable and complex ore bodies. The preferred mining method for broken ore bodies. However, both of the above two methods have difficulty in ventilation when working with multiple working faces at the same time, low production efficiency of a single working face, high labor intensity, large mining and ...
