The mining paste filling system is a comprehensive technical solution that mainly converts solid waste generated during the mining process (such as coal gangue, tailings, fly ash, etc.) into paste like slurry, and transports it to the goaf through specific technical means for filling. The following is a detailed analysis of the mining paste filling system. System Overview: The mining paste filling system achieves effective utilization of mining waste and safe filling of goaf through a series of equipment and process flows. This system not only improves the extraction rate of mining resources, but also effectively reduces environmental damage and economic losses caused by goaf collapse and tailings dam collapse. 2、 The system composition of the mine paste filling system mainly includes the following parts: 1. Solid waste treatment equipment: used for the pre-treatment of solid waste generated during the mining process, such as crushing and screening, to meet the raw material requirements for paste preparation. 2. Paste preparation system: Mix the pre treated solid waste with appropriate amounts of water, binders, and other materials, and make a paste like slurry through stirring and other processes. Paste materials usually have the characteristics of two highs (high concentration, high yield stress) and three lows (no bleeding, no precipitation, and no segregation). 3. Conveyor system: Use filling pumps and other equipment to pressurize and transport the paste slurry to the underground goaf. The conveying system needs to ensure the stability of the paste slurry during the conveying process, without any phenomena such as bleeding, sedimentation, or segregation. 4. Control system: Automatically control and monitor the entire filling process to ensure stable and efficient operation of the system. The control system can also adjust the filling parameters according to the actual situation of the goaf to achieve the best filling effect. 5. Safety and environmental protection facilities: including measures such as dust prevention, noise reduction, and leakage prevention, to ensure that the safety and environmental requirements during the filling operation are met. 3. Technical features: 1. Efficient utilization of mining waste: By converting solid waste into paste slurry for filling, the effective utilization of mining waste is achieved, reducing the accumulation of materials on the ground and environmental pollution. 2. Improve the mining rate: Paste filling can effectively support the surrounding area of the mining site, match mining operations, and thus improve the extraction rate of coal and other mineral resources. 3. Reduce environmental damage: Filling operations can reduce environmental risks such as ground subsidence and tailings dam damage, protect surface buildings and ecological environment. 4. Promoting the construction of green mines: The development of paste filling technology in mines helps to promote the construction of green mines and achieve sustainable development of mines. The four cities are in a favorable state and the development trend is trending
