260 t级硐室爆破地震测试及降震分析

根据爆破地点的地形、地质、环境条件和工程要求,通过合理地设计条形药包硐室爆破的爆破方案、爆破参数、爆破网路和微差间隔时间,较好地解决了硐室爆破震动大带来的灾害。B lastm ateⅢ型振动监测仪的测试结果表明,爆破降震取得了比较好的效果,达到了设计的预期要求。

Test of Earthquake Induced by 260 t Charge Chamber Blasting and the Vibration Reduction Measures

According to the terrain, the geology, environmental condition and engineering request of the project, the scheme, parameters, initiation network and millisecond delay intervals of the chamber blasting with linear charges were designed rationally, so that the possible earthquake disaster induced by the blasting was avoided. The results obtained by use of model Blastmate In vibration monitoring instrument indicated that the effect of vibration reduction measures was better, the expected require ment of design had been achieved.
