巷道掘进度的大小是煤矿生产的1个关键因素,EBZ255(二代)掘进机相对炮掘掘进大大提高了掘进进度,实现了巷道掘进的机械化,减轻了工人的劳动强度,确保了掘进的安全;EBZ255(二代)掘进机的检修技术标准是保证综掘机正常作业的前提。
The size of roadway excavation is a key factor in coal production. The relative heading of EBZ255 (second generation) roadheader has greatly improved the progress of excavation, realized the mechanization of roadway excavation, reduced the labor intensity of workers and ensured the safety of driving. ; EBZ255 (second generation) boring machine maintenance technical standards is to ensure the normal operation of fully mechanized mining premise.
