AI Technical Summary

Technical Problem

Existing technologies for monitoring overburden deformation in mines suffer from limitations in data acquisition, neglecting key parameters such as horizontal displacement, vertical displacement, and tilt angle. This leads to biases in the assessment of overburden deformation status and a lack of coordinated monitoring of multiple parameters, making it difficult to reflect the evolution and risks of overburden deformation in a timely and accurate manner.

Method used

The overburden is divided into multiple regions with equal area, and characteristic parameters of the overburden are collected repeatedly. Through data processing, an overburden deformation index and a comprehensive evaluation index are generated. The intrinsic relationship between parameters such as strain energy density and displacement direction angle is comprehensively considered to achieve a scientific assessment of the overburden deformation risk.

Benefits of technology

It enables dynamic tracking and comprehensive risk assessment of overburden deformation, reflecting the overburden deformation process in a timely and accurate manner, and significantly improving the accuracy and safety of overburden migration risk assessment.
