Study on Surrounding Rock Control and Fast Driving Technology of Coal Roadway
During the rapid excavation process,a large cross-section coal roadway was formed in a certain mine.This roadway has weak bearing capacity,is easily affected by surrounding mining face movements,and has poor on-site construction conditions,which seriously affects the mining continuity underground and prevents parallel projects from being carried out simultaneously,thereby affecting the production efficiency of the enterprise.To this end,numerical calculations,theoretical analysis,and on-site measurements were used to study the control of surrounding rock and the rapid excavation process of coal tunnels in a certain mine.By analyzing the geological conditions,influencing factors of surrounding rock stability,and the rapid excavation unit process of the mine,the rapid excavation process of the mine was optimized,thereby improving the production efficiency of the enterprise and ensuring safe and efficient production in the mine.
