Abstract: Thick coal seam mining in Shanxi has problems such as difficult to follow the machine, not having complete sets of equipment, low automation degree, and difficult to control the system synergistically, which is easy to cause production safety accidents.In order to effectively solve the problems in thick coal seam mining, Shanxi Huayang mine has implemented intelligent coal mining technology, making innovations in automatic coal cutting, automatic support followers, intelligent control, etc.SAC electro-hydraulic control system combined with SAP pumping station control system is applied in the coal mining face, realizing the automatic followers of underground support as well as the control of neighboring support, zoning support, and group operation; by editing the automatic coal cutting state ofcoal mining machine and adjusting automatic parameters, the automatic coal cutting of coal mining machine is realized; and the centralized control center is set up, which realizes remote control and one-key start-stop of working face equipment.Through the comparative analysis with the traditional coal mining working face, the intelligent coal mining working face improves the equipment and technology mining level of thick coal seam.
