摘要
从地震理论和工程结构动力学角度，分析了煤矿的矿山振动特点以及新生界松散覆盖层和立井结构对矿山振动的响应，从理论上证明了煤矿井下生产活动是导致立井失稳的一个作用机制，并就此种立井失稳的发展趋势和治理对策提出了见解。
Based on the theories of earthquake and construction dynamics,the characteristics of the mining vibration and its response in the quaternary covering layer and at the shafts are analyzed.It is thereotically proned that the prodution activity in the mine can be one of the factors which induce the shaft defect.In addition,the autors give more discussions about the development trends and the controlling methods of the shaft destabilization.
