摘要
A煤业回风巷在掘进过程中揭露了采空区,对其进行注浆充填后强行通过。探究了巷道掘进过采空区注浆充填区的施工方法,以及掘进通过后的巷道临时支护、永久支护和搭配的复合支护,从而确保巷道的掘进安全。
The goaf was exposed during the excavation of the return air roadway of A Coal Industry Co.,Ltd.and forced through after grouting and filling.This paper explored the construction method of roadway driving through goaf grouting filling area,as well as the temporary support,permanent support and matched composite support of roadway after driving,so as to ensure the safety of roadway excavation.
