Abstract:
Dump landslide is one of the major disasters for opencast mines, threatens the work safety of mine. Based on field research and literature analysis, this paper determined the reasonable comprehensive monitoring system for dump slope, that includes GPS, Stationary inclinometer, Rain gauge, Pore water manometer, Earth pressure cell etc. According to the request of dump early warning, early warning index systems of dump landslide were established that including single early warning indexes and comprehensive early warning indexes. Single early warning indexes include surface displacement, internal displacement, rainfall, while the comprehensive early warning indexes include main indexes and correction indexes of comprehensive early warning. According the practical situation of dump landslide accidents, scientific and practical early warning level and criteria of dump landslide were decided. The research results have contributed to strengthen safety management and accident prevention for mine dump.
