工作面输送机对综采设备无故障工作概率影响最大:工作面输送机停机时间占工作面停产时间的55％以上;刮板输送机停机时间占50％,排除牵引链故障的劳动量占53％。根据试验条件的不同牵引链寿命的变化范围很大:在有侵蚀性水的巷道中为1～1.5个月;CΠ型输送机圆环链的平均寿命为5～8个月。可见,改进牵引链运转参数的课题具有重要意义,而且是进一步完善工作面输送机的最迫切任务之一。
Working face conveyors have the greatest impact on the trouble-free working probability of fully mechanized mining equipment: the downtime of working face conveyors accounts for more than 55% of the working face shut down time; the scraper conveyor downtime accounts for 50%; the labor excluding the chain failure accounts for 53% %. According to the test conditions, the life span of different tow chains varies greatly: 1 to 1.5 months in tunnels with aggressive water; and 5 to 8 months for CΠ-type conveyor circular chains. It can be seen that the task of improving the operating parameters of the traction chain is of great significance and is one of the most urgent tasks for further improvement of the conveyor on the working face.
