Analysis of the Variation Law and Influence of Mining Pressure along the Working face Track Groove
The longitudinal groove formed by the excavation of the working face may exhibit obvious mining pressure phenomena.Understanding the mining pressure laws of the face and the roadway is of great significance for the safe and efficient production of coal mines.The working face and track groove of Changcheng No.3 Mine are monitored on-site to monitor the pressure and deformation of the groove,and then the mining pressure manifestation law is analyzed.This can provide important scientific reference for the surrounding rock support and pressure manifestation in the roadway of the mining area,and can achieve safe and efficient production of the mine.
