Problems solved by technology

However, the existing ordinary cement slurry is easy to settle in the pipeline and block the pipeline; after the slurry is in contact with coal gangue, it is prone to bleeding and segregation, and the wrapping force of gangue and other aggregates is weak, so the ability to drive aggregate flow Weak, and the amount of cement slurry used in construction is relatively large, resulting in high construction costs

Abstract

The invention discloses a cementing material for mine filling as well as a preparation method and a use method of the cementing material. The material is prepared from the following components in percentage by mass: 5-30% of cement clinker, 60-80% of fly ash, 2-15% of bentonite, 1-3% of an active activator and 0.1-1% of a modifier. The preparation method comprises the following steps: S1, weighing the raw materials; and S2, uniformly mixing all the raw materials weighed in the step S1 to obtain a mixed material, and grinding the mixed material until the specific surface area is greater than or equal to 320m <2> / g to obtain the cementing material for mine filling; the use method specifically comprises the following steps: mixing the cementing material for mine filling with water according to a mass ratio of 1: (1.5-2) to prepare slurry, and flushing the aggregate to a filling position by using the slurry until filling is completed; and the mass ratio of the cementing material for mine filling to the aggregate is 1: (10-12). The cementing material for mine filling, disclosed by the invention, has strong coating and coercing capabilities on aggregates such as coal gangue and the like, and is low in production and use cost.

Description

Technical field [0001] The present invention relates to the field of building construction materials, and more particularly to a mine filling gelling material and a method of preparing and use thereof. Background technique [0002] The existing mine filling method is generally used with cement pulp, and the slurry is fed under the well, and then the aggregate and other aggregates such as slurry, and the aggregate and other aggregates are brought into the filler region to fill the mine. However, the existing ordinary cement slurries are easy to precipitate in the pipeline; after contacting the pipe; after the slurry is in contact with the coal gangue, it is easy to generate the phenomenon in the gangue, and the wrapping force of aggregates such as gangue is weak, and the ability to flow the aggregate flow Weak, and the amount of water in the construction is large, resulting in a high construction cost. Inventive content [0003] In the case of the above prior art, the present inv...
