Abstract
The invention relates to a foaming agent for mining filling, which comprises the following components in percentage by weight: 5-10% of alkylbenzene sulfonate, 10-20% of fatty alcohol ether sulfate, 2-8% of foam stabilizer and 62-83% of water. Mixing all the components at normal temperature, and stirring. The foaming agent is used for preparing a foam tailing cemented filling material with good fluidity, increases the utilization rate of ore dressing tailing, realizes the self-flow conveying of underground pipelines, reduces the water consumption, solves the problems of serious slurry sedimentation, serious segregation and the like after the filler is dehydrated, improves the strength of the filler, and improves the underground operation environment.
Description
Technical field
The invention belongs to Mine Stope packing technique field, relate to a kind of whipping agent that filling is carried out in mine worked-out section, particularly prepare a kind of whipping agent of foam tailings cemented filling material.
Background technology
Mining with stowing is a kind of mining methods of with various suitable casting resin, the worked-out section formed in underground after ore extraction being carried out to filling.The object of bashing mainly utilizes obturator to carry out underground pressure management, to control country rock avalanche and subsidence and to create safety and condition easily for actual mining, and the environment at protection exploitation scene and the eubiosis effectively.At present, domestic mine adopts down mostly to cemented filling mining method, high density fine sand pipeline self conveying consolidated fill technique.Existing filling process Problems existing in actual production process mainly contains: filling slurry poor fluidity, needs a large amount of wash-down water in course of conveying, causes pulp density on the low side, easily produces segregation in stowing operation, affects the stable of Quality of filling body; The mud amount that Tight filling overflows is about filling total amount 5 ‰-10 ‰, not only pollute stope, and mud is mixed into ore, causes ore dilution; In addition, in slurry pipeline transport process, comparatively large to the wearing and tearing of pipeline, shorten the work-ing life of filling borehole and filling pipe.
Summary of the invention
The present invention is in order to solve the deficiencies in the prior art; object is to provide a kind of for the preparation of foam mortar compaction material; utilize the lubrication of efficient dense foam; still can guarantee the mobility of compound when low water-cement ratio, realize the mining filling whipping agent of the remote self-flowing pastefill of high density.
