A new early-warning technology based on microseism and deep sliding force comprehensive monitoring for high-steep slope landslide disaster

Abstract

Abstract The accurate and efficient identification of potential slip surfaces of high-steep slopes, monitoring of deep sliding forces, and multi-source monitoring information fusion analysis and processing are the key technical problems of slope monitoring and early-warning. A new method for accurately and efficiently identifying the potential slip surfaces of high-steep slopes was proposed to solve these problems. A refined high-constant resistance energy-absorption anchor cable monitoring device was also developed, and multi-source monitoring and early-warning information fusion discrimination criteria were established. A set of new early-warning technology for open-pit slope landslide disasters based on the combination of microseism and deep sliding force monitoring was formed. This technology was used to successfully warn about landslide disasters twice or three days in advance in the demonstration mine, which effectively guided the safety management and emergency decision making. The successful development and application of this new early-warning technology provide a new idea for the safety monitoring and control technology of high-steep slopes in China.
