Embodiment Construction
[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0023] The invention provides a method for judging the sedimentation performance of filling materials based on rheology.
[0024] The method includes steps as follows:
[0025] S1: According to the actual situation and needs of the mine, it is equipped with filling materials with different mass concentrations;
[0026] S2: Test the rheological parameters of the configured filling materials with different mass concentrations, and obtain the slurry with different mass concentrations at 0-120-0s -1 Rheological curves under shear rate conditions;
[0027] S3: According to the trend characteristics of the rheological curve obtained in S2, the sedimentation performance of the slurry is divided into three types: obvious sedimentation, basically no sedimentati...

The present invention provides a method for judging sedimentation performance of filling material based on rheology, and relates to the technical field of filling. The method firstly prepares different proportions of paste materials, according to actual conditions and needs of a mine, and then, tests paste rheological parameters under different mass concentrations, and obtains a shear stress-shearrate characteristic curve of the paste. Finally, according to rheological curve morphology, the method divides precipitation performance of the paste slurry into three stages: obvious precipitation,basically no precipitation, and no precipitation. The method has good universality for different types of filling slurry, convenient and quick detection, simple determination, and is suitable for various tailings filling slurry. The method is based on rheological experiments, enables determination of sedimentation performance to convert from the traditional qualitative determination of naked eyesto quantitative definition of the experiment, and is more instructive for actual pipeline transportation. The method is applicable to various mining enterprises adopting tailings filling technology such as colored metal, black metal, precious metal, rare metal and gold.
Description
technical field [0001] The invention relates to the technical field of filling, in particular to a method for judging the sedimentation performance of filling materials based on rheology. Background technique [0002] With the continuous increase of mining depth and the gradual enhancement of people's awareness of environmental protection, the filling mining method has been deeply rooted in the hearts of the people, and more and more mines have begun to use the filling method. During the filling pipeline transportation process, if the concentration is low, the separation of coarse and fine particles is likely to occur, and the coarse particles will gradually deposit in the pipeline along with the filling transportation, which will eventually lead to pipe plugging accidents. more likely to occur in mines. Generally speaking, increasing the filling concentration so that the coarse and fine particles in the tailings are staggered and carried by each other is an effective way t...
