华联锌铟东部排土场滚石灾害防治研究

The Eastern Dump of Yunnan Hualian zinc indium Rolling Stones Disaster Prevention Research

在分析排土场滚石运动形式的基础上,简化滚石运动模型,从运动学角度出发,总结出一套排土场滚石滚动和跳跃的计算方程。采用该方法对云南华联锌铟股份有限公司东部排土场滚石进行研究,发现阻力特性系数K取值对滚石的滚动距离和跳跃高度计算有很大影响,宜采用现场试验确定。结果表明,采用本方法得到的滚动距离和跳跃高度计算值与实测值接近,且有一定安全储备,能够为该排土场滚石灾害防治的设计和施工提供参考。

The basis of Analysis Dump Rolling Stones movement form, and simplified Roiling motion model, starting from the kinematic point of view, summed up the equations for calculating for rolling and jumping of rolling stone. The study of the eastern Dump Rolling Stones of Yunnan Hualian zinc-indium, The results show that The calculation and meas- ured values of rolling distance close to jump height when using this method , and there is a certain security reserve, so this method is able to provide a reference for the design and construction of the dump Rolling disaster prevention.
