对1211综采面回撤通道采用锚索吊棚、锚栓以及"W"型钢带进行联合支护,加强了回撤通道顶板稳定性,保证后期回撤工作安全顺利进行。
To solve the problems of broken roof and partial top falling in the retracement gateway due to the support difficulty, the author proposes the combined support with anchor-ceiling-bolt and ＂W＂-shaped steel belt at 1211 fully-mechanized mining face in Sima Colliery, which can reinforce the roof stability of retracement gateway and guarantee the safe and smooth retracement.
