Support Technology of Large Section Roadway in Coal Mining Process
Coal resources are one of China's important energy resources.However,during the mining process,factors such as the mining of huge coal mines and stress changes have led to insufficient support and serious deformation in large section tunnels.To address this problem,more in-depth and systematic research is needed.This paper first introduced the characteristics of large section roadways and the support difficulties that exist in the coal mining process,including tunnel deformation,bracket cracking,etc.Then,it analyzed the shortcomings of traditional support methods and proposed a new support technology—filling support technology.This technology uses filling materials to fill the gaps around the roadway,thereby enhancing the support effect and improving the safety and reliability of large section roadway mining.
