Problems solved by technology

However, for broken metal mines, the traditional blasting ore removal process has exposed many disadvantages. Due to the broken ore body, the allowable exposure area is small and the exposure time is short. There are low mining efficiency, large number of operators, single support method and poor safety
Especially for broken thick ore bodies, it is difficult to achieve safe and efficient mining because the ore is easy to collapse in large pieces after the blasting disturbance

specific Embodiment approach

[0030] The specific technical solutions of the present invention will be further described below with reference to the accompanying drawings, so that those skilled in the art can further understand the present invention. Such as figure 1 - Figure 5 Shown, preferred embodiment of the present invention is:

[0031] 1. Equipment

[0032] Coal roadheader 14 is an EBZ160Z roadheader developed by Shanxi Tiandi Coal Machinery Equipment Co., Ltd. for the actual situation of a gold mine. The overall dimensions are length×width×height=11.0m×2.0m×1.85m, and the weight of the whole machine is about 40t. The scraper is a WJD-1 electric scraper produced by Nanchang Kaima Co., Ltd. The overall dimensions are length × width × height = 5.8m × 1.3m × 2.0m, and the bucket capacity is 1.0m³.

[0033] 2. Specific implementation steps

[0034] (1) A gold mine is a typical broken ore body. The average thickness of the ore body 12 is 15 m, the strike length is about 200 m, the dip angle of the o...

Abstract

The invention discloses a method for mining a broken thick ore body through a coal roadway heading machine. The method comprises the steps that a vein external middle-section haulage roadway is arranged in the traveling direction of the ore body, a plurality of vein-crossing roadways are arranged perpendicular to the traveling direction of the ore body, ore chutes, pedestrian ventilation systems and filling chutes are arranged in the vein-crossing roadways, and a Z-shaped layer transfer equipment contacting road is arranged at the end of the ore body; stoping is conducted through the coal roadway heading machine, and road-entering-type stoping or successive stoping roadway by roadway or stoping at intervals is conducted in the direction of a vein; a carry-scraper follows the coal roadway heading machine to load and transport ore, and then the ore is transferred to the ore chutes; and meanwhile, waste ore cemented filling is conducted on a stoping space through the carry-scraper, filling and stoping are simultaneously conducted, and stoping and filling are balanced. The mechanization degree of the method is high, stope preparation engineering is reasonably designed, the processes ofstoping and filling are optimized, ore mining and filling continuous operation is achieved, the number of operators is decreased, the labor intensity is lowered, and thus the production efficiency isimproved greatly.

Description

technical field [0001] The invention relates to a metal mine mining method, in particular to a method for mining a broken thick ore body by using a coal roadway heading machine. Background technique [0002] The vast majority of domestic metal mining adopts the traditional blasting ore removal process, which is simple in construction, cost-saving, high in ore removal efficiency, and easy to realize mechanization and large-scale production. However, for broken metal mines, the traditional blasting ore removal process has exposed many disadvantages. Due to the broken ore body, the allowable exposure area is small and the exposure time is short. There are low mining efficiency, large number of operators, single support method and poor safety. Especially for broken thick ore bodies, it is difficult to achieve safe and efficient mining because the ore is easy to collapse in large pieces after the blasting disturbance. [0003] Coal roadheader, also known as cantilever roadheade...
