Embodiment Construction
[0024] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0025] Such as Figure 1-Figure 2 As shown, the shaft roadway system 1 for realizing thick and large ore body transportation through veins according to the embodiment of the present invention includes a plurality of mining tunnels 10 , a plurality of transportation tunnels 20 and a plurality of chute shafts 30 .
[0026] A plurality of mining tunnels 10 extend laterally along the ore body, and a plurality of mining tunnels 10 are distributed along the longitudinal interval of the ore body, and the distance between two adjacent mining tunnels 10 in the longitudinal direction of the ore body is D1. Specifically, during the mining process, the mine car can load nat...

The invention discloses a roadway system for achieving vein crossing transportation of thick and large ore bodies. The roadway system for achieving the vein crossing transportation of the thick and large ore bodies comprises a plurality of ore removal roadways, a plurality of transportation roadways and a plurality of draw shafts, and is characterized in that the multiple ore removal roadways extend in the transverse direction of the ore bodies and are distributed in the longitudinal direction of the ore bodies at intervals; the multiple transportation roadways extend in the transverse direction of the ore bodies and are distributed in the longitudinal direction of the ore bodies at intervals, the distance between every two adjacent ore removal roadways in the longitudinal direction of theore bodies is D1, the distance between every two adjacent transportation roadways in the longitudinal direction of the ore bodies is D2, D2 is larger than D1, the ore removal roadways are in communication with the transportation roadways through the draw shafts, the draw shafts are arranged at intervals in the longitudinal direction of the ore bodies, the lower end of each draw shaft is correspondingly in communication with one transportation roadway, and the upper end of each draw shaft is correspondingly in communication with the ore removal roadways. According to the roadway system for achieving vein crossing transportation of the thick and large ore bodies, vein crossing transportation of the thick and large ore bodies can be achieved, the ore removal transportation distance is shortened, the ore removal efficiency is improved, and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a shaft and roadway system for realizing the transportation of thick and large ore bodies through veins. Background technique [0002] In related technologies, for the mining of thick and large ore bodies, ore chutes are usually arranged in the ore body. The ore chutes are vertical chutes, and the lower part of the chutes is transported along the veins. This method is unfavorable for later maintenance and new excavation of the chutes. Contents of the invention [0003] The present invention is based on the inventor's discovery and recognition of the following facts and problems: [0004] In the related technology, the distance between multiple ore threading veins arranged in a thick ore body is 24-36m, the distance between two ore shafts is about 20-32m, and the distance between rail threading veins is only 20m. -32m, if the vein-piercing transportation is adopted, the turnout ...
