Abstract: Aiming at the reasonable length of empty zenith distance of continuous miner in 3103 Chahasu coal mine, the measuring instruments observed datas are analyzed, so, the final determination of reasonable empty zenith distance of drivage roadway is 7.3 m. The research results overcome the blindness of selection of empty zenith distance so as to conduct quantitative analysis on the selection of empty zenith distance and ensure that the speed and security of roadway drivage. Besides that, the above research results can provide some reference for the efficient production of coal mine.

Key words: Roadway drivage, Empty zenith distance, Continuous miner
