针对大倾角工作面支架稳定性差,易发生支架下滑、倾倒和咬架现象,通过对单支架和多支架的稳定性在不同工作状态下的力学分析,得出了支架失稳的力学机理,指出支架的失稳主要发生在降架、移架过程中,只要采取合理的支架管理措施即可保证支架的稳定性。通过采用合理的移架顺序、移架前确保相邻支架稳定、增大支架侧护板宽度、充分利用支架本身的侧护千斤顶和底调千斤顶调整支架等综合性技术措施保证了大倾角工作面支架的稳定。
In view of the poor stability of the steep working face support, prone to the glide, dumping and bite rack phenomenon, through the stability of single stents and multi-stents in different working conditions of mechanical analysis of the mechanics of the stent instability, pointed out The instability of the stent mainly occurs during the descending and moving of the stent, so long as the reasonable stent management measures are taken to ensure the stability of the stent. By adopting a reasonable sequence of moving the rack, ensuring the stability of adjacent brackets before moving the rack, increasing the width of the bracket on the side of the rack, making full use of the comprehensive technical measures such as the side jack jack of the stand and the adjusting jack of the bottom jacking jack to ensure the steep working face Stent stability.
