Study and Apply of the Support Technology for Coal Roadway with High In-situ Stress in Deep Mine

摘要：

　　Several commonly methods of the soft-rock tunnel support are introduced.According to the-850 m section coal roadway support of Jiudaoling coal mine,high in-situ stress and soft surrounding rock were chosen as the main solution.A combined supporting method of semi-circular arch bolt-anchor-metal net-steel ladder is put forward and achieved a practical support effect.
