摘要
煤层采空区,尤其是年代久远的小煤窑采空区,对隧道工程危害极大,易造成支护结构变形、开裂、沉降甚至发生坍方,个别隧道运营期间仍在整治。目前采空区隧道的设计理论尚不完善,实际设计、施工中采用的工程措施基本以工程类比及施工实践为主。文章就多年来对多个小煤窑采空区隧道的设计并结合施工实践进行了整理、归纳,取得了一些成果,以供广大隧道建设者借鉴。
The gob area of coal seam, especially the one in coal pit for ages, is extremely harmful to the tunnel project, inducing deformation, cracking, settlement and even collapse of supporting structure. And some tunnels are still being repaired during operation. Currently, the design theory for tunnel in gob area is to be improved and the engineering measures which used in practical design and construction are mainly based on engineering analogy and construction practice. In this paper the designs of some tunnels in gob areas of coal pits are summarized combined with construction practice and some achievements are obtained, which can be taken as a reference.
