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...
