Mining Engineering Roadway Excavation and Support Technology
With the increasing intensity of coal mining,the mining conditions have also undergone certain changes.The application of roadway excavation and support technology is conducive to improving mining efficiency and quality.This paper briefly analyzed the connotation,characteristics,and value of tunnel excavation and support technology,and explored the application points and commonly used tunnel support technologies of tunnel excavation technology.The research results indicate that flexible application of roadway excavation and support technology is beneficial for improving coal mine safety and reducing mining costs.Therefore,when applying roadway excavation technology,efforts should be made to control excavation intensity,gas emissions,ventilation and dust prevention,and roadway drainage.When carrying out roadway support,appropriate support methods should be selected from spray anchor support technology,shed support technology,and other means to optimize the support effect.
