摘要
崩塌落石具有突发性、随机性、隐蔽性及致灾严重性等特征。为对其进行有效防治,以某煤矿内崩塌落石为研究对象,采用RocFall软件对已崩落石的运动轨迹进行了模拟,反演拟合了下垫面参数,在此基础对拟崩落石区域进行数值模拟和理论计算得出其运动特征,为崩塌落石防治措施选择提供了合理依据。
Rockfall has the characteristics of sudden,random,concealment and disaster severity.In order to carry out effective prevention and control,Rockfall in one coal mine is taken as the research object.Rockfall software is used to simulate the movement track of caved rocks,and the underlying surface parameters are obtained through inverse fitting.On this basis,numerical simulation and theoretical calculation are carried out for the quasi caved rock area to obtain its movement track characteristics,providing a reasonable basis for the selection of prevention and control measures for rock collapse.
