Abstract:
In view of the reinforcement of roadway support and single hydraulic pillar in the poor support effect, large space and difficult management, the reinforcement technology of reinforcing anchor cable is proposed. By analyzing the mechanism of the roof falling and the surrounding rock stress and calculating the roof support strength of the mining roadway under the influence of mining, the anchor cable support design is designed. Through theoretical calculation and field practice effect, it is shown that the anchor cable reinforcement can meet the requirements of advanced roadway support under the influence of mining, and realize the purpose of roadway surrounding rock control without advance support in the working face mining roadway.
