摘要
传统的绞车回撤液压支架工艺费时费力且安全性能较差,为了提高目前工作面的搬迁效率,首次采用全新回撤装置和回撤工艺,实现了液压支架的高效回撤,降低了回撤成本,具有较高的经济和社会效益。
The traditional winch retracting hydraulic support technology is time-consuming, laborious and has poor safety performance. In order to improve the relocation efficiency of the current working face, the new retracting device and retracting process are adopted for the first time to realize the efficient retracting of the hydraulic support, reduce the cost of retracting, and have higher economic and social benefits.
