"A Method for Controlling the Filling Process in Mines" is based on the actual needs of mine filling process. It combines "traditional + advanced" control technologies to achieve precise and essential safety control of the process. It has the characteristics of high automation level and simple operation. It effectively improves the production efficiency, quality, and stability of mine filling, injecting new momentum into the development of nonferrous metal mining enterprises.
Mine filling is a common technology that involves filling abandoned mine slag, concrete, and other materials into the mine, smoothing out pits and stabilizing the foundation to achieve both environmental remediation and resource utilization goals. However, traditional mine filling techniques have difficulties in control, low production efficiency, and complex operations.
To address these issues, the company set up a professional technical team and spent several years researching and developing an automated solution that closely fits the requirements of filling in non-ferrous metal mines. This solution enables real-time monitoring and control of parameters such as material flow, liquid level, and concentration during the filling process. It automatically adjusts the proportion and flow rate of filling materials, ensuring the concentration and stability of the filling materials while guaranteeing the intrinsic safety of the filling system.

This method developed by Jinchuan Group Information and Automation not only fills the gap in relevant domestic technologies but also achieves significant breakthroughs in technological innovation, production efficiency, and environmental protection. This patented technology has been applied in three major mines of Jinchuan Group, the Wengfu filling project in Guizhou, and the Huao filling system in Hebei.
