Problems solved by technology
[0002] In the process of coal mining, for the mining of thin coal seams with a thickness of less than 0.7m, blast mining is mainly used. This mining method not only wastes resources, but also pollutes the environment, and has poor safety.
Coal plows that are usually used to mine thin coal seams have the following disadvantages: (1) The mining height range of the plow is not easy to adjust, and the adaptability to the undulation of the coal seam is poor; (2) The overall volume of the plow is large and inconvenient Mining operations in thin coal seams; (3) The planing depth of the plow head is relatively shallow, usually only 50mm to 100mm, and the mining efficiency of the whole machine is low; (4) When using a plow to mine hard coal seams, the planer (5) The friction resistance between the coal plow and the conveyor and the bottom plate is relatively large, the transmission efficiency is low, and the stability is poor
