Description

Mine tunnel transportation crossheading advance support system

Technical Field

Background

The coal mine safety regulation stipulates that the support is required in the 20m extensive surrounding of all the joints of the safety exits and the roadways, and the transportation crossheading support modes of the coal miners are mainly two at present: hydraulic single prop and self-moving advancing hydraulic prop. Both support methods have certain disadvantages in use:

1. the hydraulic single prop has the problems of low supporting strength, low supporting efficiency, high labor intensity, poor safety and the like, so the supporting mode is gradually replaced by a stepping self-moving type advanced hydraulic support in a mining area with better conditions; 2. the stepping self-moving type advance hydraulic support can reduce the labor intensity of workers and the like, but has the problems of repeated support damage to the top plate in the moving process, low moving speed and the like.

However, with the development of the coal industry in China, the coal mining depth is continuously increased, so that a large number of roadways with complex conditions appear; meanwhile, the mechanical and automatic popularization and propulsion speed is higher and higher, and the periodic pressure step distance is larger and larger.
