Roadway Strength Bolting Supporting Technology under High Stress and Soft Rock Roof of Yuwu Coal Industry
Abstract：Aiming at the difficulty of roadway supporting under high stress and soft rock roof of Yuwu coal industry,the system of high prestress strength bolt supporting is proposed.The principle of supporting design and design scheme are introduced,and the industrial test is carried out in the 2# traverse.The results show that using the combination regimen,the deformation of surrounding rock is controlled effectively and the stability of surrounding rock is also improved.
