The invention relates to a paste combined filling method utilizing solid wastes of a mine. The method comprises the following steps of: constructing a filling retaining wall at the inlet of an underground worked-out section, and filling waste stones in which target metal is not contained or the content of the target metal is less than a boundary level, wherein the lumpiness is 0 to 400 millimeters, the loose static angle is 40 to 45 degrees, and the filling volume rate of the waste stones is 10 to 45 percent; then mixing 6.25 to 21.25 weight percent of gelatinizing agent, 53.75 to 78.75 weight percent of filling aggregates and 15 to 25 weight percent of water into a stirrer so as to prepare a paste cement material with the weight concentration of 75 to 85 percent; and conveying the paste cement material to the worked-out section through pumping of a filling pipeline or self-flowing under the action of gravity along the filling pipe, wherein the paste cement material is penetrated into the ...

Continuous type mixing apparatus of dry powder mortar

The utility model relates to a continuous type mixing apparatus of dry powder mortar, including feed cylinder, mixer and conveyor screw, feed cylinder, mixer and conveyor screw supreme and connect down in proper order, the feed cylinder includes barrel and blanking baffle, the blanking baffle sets up in the feed cylinder along the blanking direction crisscrossly, the mixer includes the casing, sets up the pivot in this casing to and a plurality of rotating blade s of equipartition in this pivot circumference direction. Beneficial effect does: by a section of thick bamboo, the three sets of device combination of mixer and conveyor screw of gathering materials, realized that the cubic of material mixes. It is that mixing process goes on in succession to mix the machine different with the conventionality, and the mixed phase is to evenly, has improved the production efficiency of dry powder mortar in the very big degree. A complete set of equipment power consumption is only for about 15kw.
