摘要:

摘要:刮板输送机上窜下滑是综采工作面经常出现的问题。本文通过刮板输送机受力分析,认为其“上窜下滑”的主要是由于输送机受力不平衡造成的,所受合力表现为下滑力时,输送机出现下滑,合力表现为向上方向的力时,输送机则出现上窜。并提出工作面伪倾斜开采是控制刮板输送机“上窜下滑”的主要技术措施,通过在张集矿1412(3)工作面实践,取得了较好效果。

Abstract:

Abstract: The trouble of scraper conveyor moving up and down often occurs in fully mechanized mining face. This paper considers that the major reason is imbalanced stress of scraper conveyor, when the join force is upward, the scraper conveyor moves up. The main method of controlling scraper conveyor is false inclination mining, practicing in the 1412(3)working face and the effect is remarkable.
