Abstract:

In order to improve the stability and safety of roadway in mining engineering, after nearly 60 years of research and continuous optimization at home and abroad, the theory and practice of lining roadway and surrounding rock control have accumulated rich achievements. This paper deeply analyzes the application of lining roadway in different mining modes, such as forward, regressive and reciprocating mining. At the same time, it elaborates on the five key surrounding rock control technologies of lining roadway, namely surface support, anchorage, modification, pressure relief and joint control. On this basis, the paper further discusses the application scenarios of filling and top-cutting lining roadway. In particular, in the practice of filling lining roadway, by comparing with other filling materials and methods, the unique properties of high water material and their application characteristics in the filling process are deeply analyzed. Experiments and field data fully prove that the filling technology of high water material can effectively strengthen the structural strength of roadway, significantly reduce the risk of safety accidents, and significantly improve the recovery rate of coal resources. In addition, this paper also studies the construction technology of this technology, including the key elements of material proportioning and filling methods. The research provides important guidance for the practice of mining engineering, and lays a foundation for the further development of this technology.
