Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Such as Figure 1-Figure 2 As shown, the method of the present invention divides the panels along the ore body trend, and in the panel area, a number of ore blocks are arranged along the inclination, and the height of the middle section is 25m. , 4 to 6 ore blocks are arranged in each panel, the ore blocks are 40 to 60m long in the strike direction, 40 to 60m long in the dip direction, and the width is the thickness of the ore body. There are 7 regular pillars in the field, and the size of the pillars is 3-5m×3-5...

Abstract

The invention discloses a mechanical mining method of a near-horizontal thin ore body by an intelligent heading machine. The mechanical mining method comprises the following steps of: 1) dividing a panel along the trend of the ore body, and arranging a plurality of ore blocks in the panel along the inclination direction; 2) stoping each ore block by the intelligent heading machine, and reserving a space pillar, a point pillar and a bottom pillar during stoping of the ore blocks by adopting a room-pillar mining mode; 3) dividing the interior of each ore block into a plurality of vertical layers along the inclination direction, wherein the vertical layers are divided into a non-point-pillar layer and a point-pillar layer, and the point pillar is reserved in the point-pillar layer during stoping; 4) stoping the interior of each ore block layer by layer from bottom to top according to the vertical layers, and mining another ore block at the upper part after one ore block is mined and filled. The method disclosed by the invention is suitable for mining the near-horizontal thin ore body with the thickness of 3-8m and the medium stability, and a new method is provided for non-explosive continuous mechanical mining.

Description

technical field [0001] The invention relates to the technical field of non-coal mining, in particular to a mechanical mining method with an intelligent roadheader for a near-horizontal thin ore body. Background technique [0002] For the mining of thin ore bodies under medium stability and near horizontal, the conventional drilling and blasting method has disadvantages such as poor safety, poor operation continuity, small production capacity, low degree of mechanization, low degree of intelligence, and high loss and dilution rate, etc., and urgently needs to be improved. Traditional recovery process. [0003] The cantilever roadheader is a large-scale and efficient combined operation machine that integrates multiple functions such as cutting rocks, loading, transporting ballast, and dust reduction. Due to the advantages of good cross-section forming quality, high safety, high production efficiency, less personnel requirements, and low labor intensity, it has always been the...
