The invention provides a full-potential paste filling system and method for a coal mine goaf. The system comprises pulping equipment, waste rock supplying equipment, a slurry conveying pipe (7) and a high-pressure hose (11), wherein one end of the high-pressure hose (11) is connected with the slurry delivery pipe (7); the high-pressure hose (11) can guide slurry discharged from the slurry delivery pipe (7) to branch lanes (13) to be filled. The full-potential paste filling system and method for the coal mine goaf fully utilize filling materials of waste rocks, cement, coal ash and the like which are wide in source, and adopt a full-potential paste filling technology for the coal mine goaf under buildings, railroads and water bodies, and the full-potential paste filling technology is simple in process equipment, high in efficiency, low in investment, low in cost and sustainable.
Description
technical field [0001] The invention relates to the field of mining technology, in particular to a full potential energy paste filling system for goafs in coal mines, and a method for filling paste with full potential energy terminal pipelines for coal mining. Background technique [0002] According to incomplete statistics, the "three downs" (under buildings, under railways, and under water) of my country's production mines have produced 14.3 billion tons of coal. With the rapid development of my country's economy, the development and utilization of coal resources is getting higher and higher. , "Three under" pressure coal mining is the main problem faced by coal mining. For a long time, my country has mainly used several methods such as village relocation, strip mining, water-sand filling, and overlying rock separation layer grouting. In particular, the filling mining method is backward in technology, and the filling cost is high, which is difficult to maintain and promote...
