Problems solved by technology

[0004] The purpose of the present invention is to solve the long-standing problems in the mining industry that the cycle of digging first and then mining is too long, and that personnel, equipment and existing resources cannot fully play their roles. A production method in which the two processes are carried out at the same time and the mining lanes are reused

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the technical solution. see figure 1 . The original mining method is: on both sides of the working face 2 to be mined, two horizontal roadways with a depth of more than one thousand meters are excavated in parallel in the direction perpendicular or approximately perpendicular to the main air inlet and exhaust roadway. In the mining position, the two lanes are connected by a cutting eye 9. Transportation equipment is installed in the roadway 6, which is also called a level road, and it is connected with the main air inlet roadway 4. Another roadway is mainly used for transporting equipment, passes through etc. for the staff, is called track 7, and it links to each other with another main exhaust roadway 5. The layout of the main air intake and exhaust roadway and the mining face roadway is very similar to the Chinese character "non". The wind flow in the roadway forms a flow along the direction...

Abstract

The invented mining method includes the following steps: using two working faces to be mined as one group, firstly, at two sides of working face to be mined, back towards main tunnel of mining area driving tunnel in depth, then making mining direction be identical to tunnel-direction and further driving in depth, after the mining-stopping line is reached, changing the tunnel-driving trend into semi-circular form or arc form, transferring working face and driving in the mode of fan-shaped form, after the working face is rotated to 180deg. and the secondary heading of semi-circular trend is communicated with main heading of the working face, mining towards direction of main tunnel of mining area to make back production.

Description

(1) Technical field [0001] The invention discloses a mining method related to underground mineral deposits, in particular to a production method in which roadway excavation and mining are carried out synchronously. (2) Background technology [0002] The vast majority of underground deposits are in inclined positions. Large-scale mines have multiple mining areas, and each mining area must have at least two main roadways for air intake and exhaust. The mining working faces are arranged vertically or nearly vertically on the two wings of the main roadway, just like the word "non". The two verticals are the main air intake and exhaust roadways, and each horizontal line is a mining working face. And there are two roadways on both sides of each mining face, used as air intake and exhaust. Generally, the roadway connecting the main air inlet roadway with the roadway on one side of the mining face is called a flat roadway, which plays the role of air intake and product output. Th...
