This is an essential material for the basic performance research of filling goaf, so countries have conducted in-depth research on it. 3. Developing efficient mine filling equipment and improving the automation level of mine filling automatic control system directly affects and restricts the development of mine filling mining technology. However, due to the poor technical performance stability of domestically produced related equipment, the development of mine filling technology has been hindered. Therefore, it is necessary to strengthen the development of efficient thickening equipment (such as high-efficiency thickeners, ceramic filters, vacuum filters, disc filters, etc.) to provide effective guarantees for the manufacturing of high concentration tailings slurry, and to study methods to reduce or eliminate wear and corrosion of filling equipment. More importantly, it is necessary to develop high concentration conveying equipment and use pressure discharge equipment to adjust the conveying pressure of each section to prevent pipe blockage during transportation. The most crucial step in normalizing the automatic control technology for the discharge concentration and material flow rate of the filling system is to develop and introduce automation equipment and instruments suitable for mining applications, establish a true automatic control system, and adjust the flow rate of tailings discharge, filling solidification materials, and clean water in the filling system to automatically adjust the filling concentration.
