NOUFERROUS METALLURGICAL EQUIPMENT

In the process of mine filling and mining operations, the strength of the filling body in the goaf is directly related to the safety, stability, and economic efficiency of the mine. In response to the current issue where the strength of the filling body in filling engineering fails to meet design requirements, this paper conducts an in-depth analysis of the working characteristics of commonly used filling slurry mixing equipment and systematically investigates the types and composition ratios of different filling aggregates. Based on this, an innovative“high-efficiency activation + low-speed mixing” combined slurry mixing process is proposed. This process formulates corresponding mixing methods for filling slurries composed of different aggregates, significantly enhancing the adaptability and flexibility of the slurry preparation system. The research findings provide an effective technical approach for improving the strength of the filling body, ensuring the safety and economic efficiency of the mine, and hold high reference value for the industry.
