ABSTRACT
This paper presents a methodology for analysing the state of an inclinometer tube used for in-situ monitoring of the relative slide between backfill and surrounding rock mass, based on the principles of elastic beam and elastic foundation beam theory. Through the utilisation of this approach, it becomes feasible to evaluate the appropriate depth for installation, the extent of measurement, and the operational state of the inclinometer tube. The mechanical response of the inclinometer tube was analysed using the new method and finite element method, with Longshou Mine serving as the background. The feasibility of the new method was subsequently confirmed.
