Internal combustion road cutting machine, concrete pavement cutting machine instructions, gasoline-type project cutters, portable light road cutting machine recent years, the world is giving new energy to do internal combustion cutter "addition", while China's coal industry has followed suit. " addition ", but also in the coal market inflection point on the upcoming project continues. Also the depth of concrete cutting machine, the elimination of backward production capacity in the process, many places have been advanced in the construction of large coal mines, but progress has been slow in doing subtraction Shique. Under the combined effect of these factors, the coal industry overcapacity problem intensified the. Concrete cutting machine for use in coal industry development trend, "worsened", the coal market oversupply contradiction, inventories, prices fell, increasing pressure on business.
