Description

Mine roadway grooving machine

Technical Field

The utility model relates to a well worker mining equipment especially relates to a mining tunnel groover.

Background

Coal seams in China have various occurrence conditions, including medium-thickness coal seams and thin coal seams, and different mining conditions, and coal mining scales, technical equipment and mining modes in different areas have great differences.

Thin coal seams represent a significant proportion of the currently proven reserves. All equipment put into the well must be miniaturized, since the coal seam is much more difficult to mine. The conventional grooving machine in China at present cannot be suitable for the grooving operation of a thin seam roadway, temporary wind walls are built, permanent closed wall bodies are grooved, the work of combining roadway excavation and water suction pump pit and drainage ditch is realized by picking manually by the most original method, and the manual excavation is realized by the pneumatic pick. The air pick has high noise and high labor intensity of workers, particularly, the top excavation is more difficult and the efficiency is very low, and the flying coal blocks easily hurt constructors. Because the construction of the tunnel bottom is more difficult, the quality and the size of the opened notch effect are very poor, generally, the closed wall body is opened, two persons operate the closed wall body, and the working time of opening one notch can be generally finished in 5 to 7 working days. At present, no mature special thin coal seam roadway grooving equipment exists in the field of thin coal seams at home and abroad.
