摘要
排土场滑坡是矿山的重大灾害之一,威胁矿山的安全生产。本文在现场调研和文献分析的基础上,确定了合理的矿山排土场边坡综合监测系统,其中包括GPS、固定式测斜仪、雨量计、孔隙水压力计等仪器。根据排土场预警的需求,建立包括单一预警指标和综合预警指标的排土场滑坡预警指标体系,单一预警指标为地表位移、内部位移、降雨量,综合预警指标包括综合预警主指标和修正指标。根据排土场滑坡事故的实际情况,确定科学、实用的排土场滑坡预警等级和预警准则。本研究成果有助于加强矿山排土场的安全管理和事故预防。
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.
