矿山排土场滚石运动规律及其灾害防治的研究

Investigation on the Motion Law of the Rolling Rock in Mine Dumps and Its Destruction Prevention and Control

本文针对露天矿排土场边坡滚石运动的实测数据运用能量守恒和动量矩原理进行分析研究，论述了滚石运动产生和中止的具体条件，影响滚石运动状态的诸多因素；初步计算出滚石沿排土场边坡滚动的速度、动量、最远滚动距离、弹跳高度等运动轨迹；详细探讨了滚石运动规律；滚石具有很大的破坏力，会造成灾害，须予以高度重视。提出了防治滚石破坏的具体措施，以减少或消除滚石造成的危害。

Analysis and study are made by the laws of energy conservation and momentum moment on the practical measurements of the rolling rock movement along the dump slope in a metallurgical open pit mine The specific conditions of the occurence and cease of the rolling rock movement and a number of factors that affect the rolling rock state are described, and the motion parameters and motion track of the rocks rolling along the dump slope are calculated in a preliminary way, such as velocity, momentum, the farthest rolling distance and spring height Detailed discussion is made on the motion law of the rolling rock and it is pointed out that rolling rocks can have great destroying force and can even cause a disaster,which should be paid great attention to Therefore, concrete measures are suggested for effectively preventing and controlling the destruction caused by the rolling rocks so as to reduce and eliminate its endanger
