Time-domain reflectometry–based real-time slope stability monitoring in opencast mines: A review

Abstract

Time-domain reflectometry plays a crucial role in slope stability. Slope stability factors are an important parameter in the mining regions over opencast mine slope failure. Conventional methods are oldest as well as poorest risk assessments for monitoring and predication over slope failure conditions. Time-domain reflectometry application has been used among various fields of research at different areas of interest. But, it is implemented in mining area at opencast mines for phonographic review over slope failure conditions. This is a recent technology with low cost, which uses a wireless transmission system for high-risk assessment over slope stability measurement by received signal strength indicator. Moreover, this research is more suitable for monitoring of slope stability as well as less complex about time-domain reflectometry application of installation and real-time slope stability monitoring. The review case of time-domain reflectometry application is linked into the mining area. So, this result is best suitability of time-domain reflectometry and the Internet of things for real-time slope stability monitoring in opencast mines.
