Abstract
The present disclosure relates to the field of survey and stability evaluation of a tailing fill dam, in particular to a method and system for survey and stability evaluation of an upstream tailing fill dam, wherein the method comprises the following steps: selecting a drill bit and a soil sampler for a target tailing fill dam; collecting tailing sand at different depths of the target tailing fill dam using the drill bit and the soil sampler; detecting an undisturbed soil sample of the tailing sand; setting a preset standard according to the undisturbed soil sample, and screening the tailing sand using the preset standard to obtain a tailing sand sample; detecting the particle composition of the tailing sand sample; detecting the mechanical property of the tailing sand sample; and evaluating the stability of the target tailing fill dam through the particle composition and the mechanical property.
