Abstract
Description
Technical field:
[0001] The invention relates to underground mining equipment, in particular to a mining roadway slotting machine. Background technique:
[0002] Coal is the cornerstone of my country's energy security and is of great importance to national economic security. The occurrence conditions of coal seams in my country are various, including medium-thick coal seams and thin coal seams, and the mining conditions are different. There are great differences in the mining scale, technical equipment and mining methods of coal mines in different regions.
[0003] Thin coal seams account for a large proportion of the current proven reserves. Since the thin coal seam brings greater difficulty to mining, all the downhole equipment must be miniaturized. At present, the existing slotting machines in China are not suitable for slotting operations in thin coal seam roadways. Temporary building of wind walls, slotting of permanently sealed walls, digging of water pump nests in j...
