Abstract
The invention relates to a high-concentration full-tailing cemented filling system which comprises a filling subsystem arranged on the earth surface of a to-be-filled area, a pipeline subsystem connected with a filling device and a control subsystem connected with the filling subsystem. The filling subsystem comprises a deep cone thickening device, a cement device and a stirring device, the pipeline subsystem comprises a horizontal pipeline and a vertical pipeline, the deep cone thickening device is connected with the stirring device through the horizontal pipeline, the cement device is connected with the stirring device, the stirring device is communicated with a to-be-filled area through the vertical pipeline, and the gradient of the vertical pipeline 160 is smaller than or equal to 1 degree; the control subsystem comprises a sand slurry control device, a sand level control device connected with the deep cone thickening device, a cement bin level control device connected with the cement device, and a stirring liquid level control device connected with the stirring device; according to the invention, by arranging the control system, accurate determination of the optimal ratio is realized.
Description
technical field [0001] The invention relates to the technical field of mine tailings filling, in particular to a high-concentration full tailings cemented filling system. Background technique [0002] The filling mining technology that makes extensive use of mine solid waste can not only recover resources safely and effectively, preserve prospective resources, prevent surface collapse, but also reduce the discharge of solid waste to the surface. It is a direct and effective way of environmental protection and waste recycling, and it is a strategic new technology to support the sustainable development of mining in the modern mining industry. Therefore, the no-waste or less-waste mining technology has a huge market in my country's metal, non-metal, building materials, chemical and other mines, and has broad application prospects. This is because my country's environmental protection requirements are getting higher and higher, which makes many mines must implement waste-free m...
