摘要
针对复采工作面沿空留巷巷道顶板和帮部破碎及受多次动压影响的问题,提出了架棚支护的5种形式。针对不同的支护形式,对顶板和帮部的联接部分进行强度计算,提高了支架的整体稳定性和可操作性,为复采工作面沿空留巷巷道支架选型提供了思路。
In view of the broken roof and side and the influence of multiple dynamic pressure of gobside entry retaining roadway in repeated mining face,five forms of shed support were put forward.Aiming at different support forms,the strength of the connection part of the roof and the side was calculated to improve the overall stability and operability of the support,and provide ideas for the selection of roadway support for gob-side entry retaining in repeated mining face.
