Abstract: As the development of mining engineering ,the filling technology used gangue as filling aggregate is being studied and applied.In order to solve the problems of general rheological instruments can not test the parameter of slurry for the relatively large size of gangue in general. The use of existing laboratory mixers and power meter and power sensor considered the the traditional rotational viscometer as the parameter calibration instruments for self-calibration rheometer to identify the correlation between the two conversion coefficients, as well as self-rheometer for testing formula then measured coarse aggregate slurry rheological parameters, and analyzed the reasons for self-rheological instrumental error.

Key words: gangue, paste-like, filling slurry, rheological parameter, rheometer
