Embodiment 1

[0052] Embodiment 1, as Figure 5 , 6 7. Shown in 7: Dahongshan Iron Mine Underground 4000000 t / a Mining Phase 1 Project Tape Inclined Shaft Development System, the main Tape Inclined Shaft section is set on the flank of the main ore body, consisting of 4 sections (2 sections underground, 2 sections on the surface) Section), adopt the setting method of rail maintenance road in the same wellbore.

[0053] The project adopts the belt inclined shaft-trackless ramp-auxiliary blind shaft joint development method. The ore belt transportation system from the underground to the surface dressing plant is composed of 4 sections of belt, that is, the short belt conveyor section 5 protected by ore protection, and the two main sections. Belt inclined shaft sections 7-1 and 7-2 are composed of ore unloading point reloading conveyor section 8, which is set on the flank of main ore body 1. Mined ore is crushed by underground crushing station 2 and then sent to crushed ore bin 3. The ore fee...

Embodiment 2

[0055] Embodiment 2, as Figure 8 , 9 10 and 10: The ore body mined in the second phase of the deep part of Dahongshan Iron Mine has a buried depth of about 700-1000m, and the development system adopts the joint development method of tape inclined shaft-trackless ramp-auxiliary shaft.

[0056] The main belt inclined shaft section is set in the middle of the flank of the main ore body 1, and consists of 7 sections (5 underground sections, 2 surface sections), the ore-protected transfer short belt conveyor section 5, and the five-section turn-back type main belt inclined shaft section 7-1, 7-2, 7-3, 7-4, 7-5, and unloading point transfer conveyor section 8, adopting the setting method of setting trackless maintenance road in the same shaft; the total lifting height reaches 783m, The total length is about 5000m, and the transportation capacity is further increased to 6 million t / a, 1250t / h.

[0057] in:

[0058] The inclined shaft section 7-1 of the main tape has an inclinati...

Embodiment 3

[0064] Embodiment 3, as Figure 11 , 12 , 13 shown. The first phase of the Dahongshan Copper Mine project has an ore body with a buried depth of more than 300m. It adopts the method of setting up railed auxiliary inclined shafts in parallel with the belt inclined shaft to form parallel double inclined shafts. The auxiliary inclined shaft is used as the inspection channel for the belt conveyor in the belt inclined shaft. . The transportation volume reaches 4 million t / a, 13000t / d.

[0065]

[0066] The main belt inclined shaft is set on the flank of the main ore body 1, and consists of 5 sections (2 sections underground, 3 sections on the surface), the section 5 is protected by the ore-protected transshipment short belt conveyor, the three-section turn-back type main belt inclined shaft section 7-1, 7-2, 7-3, and the ore unloading point reloading conveyor section 8 are formed, and the rail auxiliary inclined shaft shaft 12 is arranged in parallel with the tape inclined shaf...

Abstract

The invention relates to the exploration and transportation technology of an underground metal mine, in particular to an adhesive tape inclined shaft. In order to solve the problem caused when the adhesive tape inclined shaft is exploited in the metal mine of which the exploitation scale is large and the exploitation depth is high, the invention provides a way of using the adhesive tape inclined shaft to perform exploitation transportation in the underground metal mine under the condition. The adhesive tape inclined shaft is characterized in that: the whole adhesive tape conveyor section consists of the adhesive tape inclined shaft and an adhesive tape conveyor, is generally arranged outside an ore body and consists of an ore protection and transfer short adhesive tape conveyor section, a main adhesive tape conveyor section (one section or a plurality of sections) and an ore discharging point transshipping conveyor section. The conveying amount of the adhesive tape conveyor is large, and the conveying distance of the adhesive tape conveyor is long. A high-layer shaft tower is not required to be arranged on the ground surface; and a driving station is simple in structure, low in investment and short in construction period. A driving, controlling and detecting system is high in automation degree, relatively simple in structure and low in investment. The cost for the inclined shaft is lower than that for a vertical shaft; after being damaged, an adhesive tape can be replaced in sections; and the operation cost is low. The adhesive tape inclined shaft exploitation way has a good economic benefit.

Description

technical field [0001] The invention relates to the mining and transportation technology of underground metal mines, in particular to tape inclined shafts. Background technique [0002] For metal mines using underground mining methods, when the ore body occurs below the ground, and as the burial depth increases, adit development cannot be used, in the past, vertical shaft development or inclined shaft development was generally considered, and vertical shafts or inclined shafts were used as the main mine respectively. The ore is lifted in the well, and it is matched with auxiliary lifting shafts such as auxiliary cage shafts, adit, trackless ramps, and inclined shafts for string cars to form a corresponding development method. [0003] Common shaft development methods and their limitations: [0004] The cage shaft is intermittent lifting and can only be used for auxiliary lifting or ore lifting in small mines. [0005] Although the skip shaft can be used for ore hoisting in...
