摘要(Abstract)：

采用抛掷爆破法加固高危尾矿坝获得成功，该工程在我国尚属首例，其技术居国内领先水平。该成果揭示了细粒级尾砂在强烈爆破震动下的液化反应规律及坝体不均匀沉降引起的剪切破坏机理，提出了抗液化、抗失稳的判据及技术措施，可供同类型工程借鉴
The success of application of throw blasting in stabilizing a very dangerous tailing dam is the first case in China.This technology is advanced in leading level in China.The shear failure mechanism are caused by the “Liquidity”reaction rules of fine tailing sand under theexplosion shatter and uneven subsidence of the dam body.The judgment and technical methods of anti-liquidation and anti-instability were given.It is able to be a method for the other engineering in the same way as reference.
