Abstract:
In order to improve the efficiency of rapid excavation of the first mining working face coal roadway in the south wing of Zhundong Second Mine in Xinjiang,the factors affecting the stability of surrounding rock such as excavation mechanical parameters,coal seam hardness,structural characteristics and others during the rapid excavation process are analyzed in depth.Through a series of measures such as precise geological evaluation,parameter optimization of excavation machine set,synchronous cutting and support,as well as real-time monitoring and emergency adjustment,etc,the rapid excavation of coal roadways and effective surrounding rock control under complex geological conditions are achieved,providing valuable reference and guidance for the excavation of similar working faces.
