大高差综放面设备控制及调整工艺研究

Study on Equipment Control and Adjustment Technology of Fully Mechanized Caving Face with Large Height Difference

综放工作面两巷高差过大时,容易造成支架歪斜和刮板输送机前后窜问题,严重时易造成支架倒架和工作面机头机尾割不透导致停产事故.针对上述情况,我们摸索出了一系列的测量方法和调整办法,并确保了工作面正常推进.

When the height difference between the two roadways in fully mechanized top-coal caving face is too large,it is easy to cause the problems of support skew and scraper conveyor channeling back and forth.In serious cases,it is easy to cause support inversion and the failure of cutting the head and tail of the working face,leading to shutdown accidents.In view of the above situation,we have explored a series of measurement and adjustment methods,and ensured the normal advance of the working face.
