Abstract: According to the surrounding rock stability decreased, the equipment power and dimension highly increased in the 8 m high cutting coal mining face, bas ed on the real-time, accuracy and adaptation of the control, a more higher requirements were provided and a study was conducted on the intelligent control technology of the ultra high cutting coal mining face. Based on the pressure and inclination sensors set on the hydraulic powered support, a support status online monitoring syste m of the hydraulic powered support was established.Based on the memory cutting and high accurate location control of the coal shearer, an automatic coal cutting was realized with the modified mining and cutting curve. An intelligent driving strategy with the multi motor power coordination of the scraper conveyor was provided, A three supply and three returned loop hydraulic supply and the high pressure automatic compensation technology was applied to realize the intelligent control of the min press ure fluctuation of the power system and the max transient hydraulic supply. Those above technologies were applied to Jinjitan Mine of Yankuang Group Company Limite d. The results showed that the coal wall spalling, insufficient setting force of the hydraulic powered support, the scraper conveyor jammed and other problems were obvi ously reduced, three-stage sidewall protection time was reduced by 1/2, the operation quality and efficiency of the equipment were efficiently improved and the control r equirements of the ultra high cutting coal mining face could be efficiently met.
