The invention discloses an underground filling admixture mixing device and belongs to the technical field of mine filling processes. The device is characterized by comprising an admixture container, apressurizing device, a filling pipe and an admixture mixing device; the admixture mixing device is arranged on the filling pipe; the admixture container, the pressurizing device and the admixture mixing device are sequentially connected through an admixture conveying pipe. According to the underground filling admixture mixing device disclosed by the invention, the problems of admixture adding, uniform mixing and rapid conveying can be well solved; and therefore, the filling roof contact rate is greatly improved in actual production, the production safety risk is effectively reduced, the economic benefit of a mine is improved. The device is reasonable in design, simple in structure, convenient to manufacture, low in application cost, good in effect, worthy of application and popularizationin various mines and high in practicability.
Description
technical field [0001] The invention belongs to the technical field of underground mine filling technology, and in particular relates to an underground filling admixture mixing device. Background technique [0002] In recent years, the filling mining method has been widely used in metal mines and non-metal mines, which has avoided the occurrence of large-scale disasters such as surface subsidence, ground collapse, rockburst, and rock fall (roof fall). The filling operation of underground mining is to fill the goaf with artificially formed filling body, solve the transmission and adjustment of unbalanced stress in the stope, and make the stress field of the original rock reach a stable state again, which is an important process in the pre-mining preparation operation . In the actual filling process, due to various factors such as slurry segregation, filling body bleeding and settlement, irregular goaf roof, and human factors, the rate of filling and roof connection in goafs ...
