Coal Mine Roadway Excavation Advanced Support Equipment

Coal is an important chemical energy source, and it is still the basic energy source for human beings in the short term. At the present stage, human demand for coal resources is increasing, so coal mine production is of great significance. Among them, roadway excavation is an important part of coal mine production, and advanced support equipment is the key link to ensure roadway excavation. This study aims to provide a comprehensive overview of the classification, characteristics, and development of existing coal mine roadway advanced support. In this study, we review the existing coal mine roadway advanced support technologies. According to the relevant patents, we analyze and summarize the characteristics of each patent, to predict the development trend of coal mine roadway advanced support in the coming period. This paper collates and analyses the existing advanced support methods, and summarizes four types and their typical characteristics. It analyses the main problems in the advanced support used at the present stage, collects and researches the relevant patents, and discusses the research status and future development trends of various advanced support methods. According to our research, advanced support equipment can be divided into independent advanced support equipment, advanced support equipment in conjunction with a tunnel boring machine, advanced support equipment in conjunction with an anchor drilling machine, and intelligent advanced support equipment. Independent advanced support has the advantages of simple structure and convenient operation. The advanced support equipment with a tunnel boring machine and the advanced support equipment with an anchor drilling machine can work more efficiently through cooperation with the drilling rig and other equipment. With the progress of science and technology, intelligent advanced support equipment has become the mainstream direction of future development.
