Problems solved by technology

[0002] When the coal mining face encounters a soft coal seam floor, manual undercover is required to maintain the height of the roadway as the working face advances. Even under normal operation, it is often necessary to manually clean the floating coal under the loader and belt conveyor to maintain normal production. The labor intensity of the workers is high. In the production process, a large number of materials and accessories are currently loaded and unloaded by manual chain hoists. The roots of the chain hoists need to be lowered to the shed or lifted by the anchor rod. Not only the workload is large, the efficiency is low, and the material is wasted. , the more important thing is that the manual operation below the root lifting point has a great potential safety hazard
During the installation of fully mechanized mining and caving working face equipment, the installation and unloading of the front and rear chutes are currently lifted and aligned by manual chain hoists. A total of 200-300 lifting anchors need to be drilled in the cutting hole of the working face, and the roof condition is poor. Sometimes it is necessary to step down from the shed to strengthen maintenance. There are also heavy physical labor, low efficiency, serious waste and potential safety hazards.
