Research on prevention and control strategy of end slope collapse disaster in open-pit mine
LU Qingchao
Abstract：In order to quickly solve the problems such as road transportation interruption and threat to the safety of operation equipment and personnel caused by the collapse and instability of the open-pit end slope,taking the local collapse of the east end slope in Antaibao Open-pit Mine as an example,the article constructs a typical slope engineering geological model of the study area,and studies the typical failure and instability model of the end slope rock slope by combining numerical simulation and limit equilibrium analysis,evaluatesand predicts the stability of slope.From the technical and economic aspects,the article compares and analyzes control effects and advantages and disadvantages of the measures such as slope cutting and load reduction,main road reconstruction and monitoring and inspection,and puts forward the rapid response measures combining"main road reconstruction"and"monitoring and inspection"to ensure open-pit mine safe and efficient production.
