Application of Grouting Reinforcement Technology in Fully-mechanized Mining Face Passing through Goaf Roadways
Through a comprehensive understanding of the challenges faced by fully-mechanized mining face passing through goaf roadways and the development process of grouting reinforcement technology,the grouting materials,equipment and working principle were explored,and the effectiveness of grouting reinforcement technology in actual operation was highlighted by combining concrete engineering practice cases.The advantages and limitations of the technique were compared,the practical effect on roadway stability was emphasized,and the direction of future research was put forward.The purpose of the study is to provide practical guidance for promoting grouting reinforcement technology in coal mine engineering,so as to improve the overall safety and benefit of coal mine engineering.
