刮板输送机是一种有挠性牵引机构的连续运输机械,担负着综采工作面原煤运输的主要任务。其优点是:坚固结实,经久耐用;能水平和垂直弯曲,以适应采煤工作面底板不平和弯曲移设的需要;机身矮,便于装煤,适应各种煤层的需要,尤其在神南大采高工作面更能发挥其重要作用,它支撑起现代化高产高效综采工作面的半边天。其缺点是在使用过程中因自身原因或设备操作者的原因经常发生断链事故,处理难度大,影响生产时间长。本文就神南矿区张家峁煤矿15201-15204四个5-2煤综采工作面发生的刮板运输机断链事故的原因进行了分析并提出了可操作性极强的预防方法。
Scraper conveyor is a flexible traction mechanism of continuous transport machinery, responsible for the comprehensive mining face of coal transport the main task. The advantages are: solid sturdy, durable; horizontal and vertical bending to meet the coal mining floor uneven and curved shift needs; short fuselage, easy to load coal, to adapt to the needs of a variety of coal, especially in the Shennan Mining face more play an important role in its support of modern high-yield and high efficiency fully mechanized mining face half the sky. The disadvantage is that in the course of its use, the chain scission accident often occurs due to its own reasons or to the equipment operator, which is difficult to handle and affects the production time. In this paper, the causes of chain scission accident of scraper conveyor occurred in four 5-2 coal fully mechanized mining face of Zhangjiajie Coal Mine in Zhangjiajie Coal Mine of Zhangjiajie Coal Mine of 15201-15204 in Shennan Mining Area are analyzed and the methods of prevention with strong maneuverability are put forward.
