控制硐室爆破飞石安全问题措施探讨

Discussion of the Measures of Controlling Flyrock Caused by Coyote Blasting

硐室大爆破产生个别飞石的原因,主要有测量不准确、地质条件不清楚、药包布置不合适、爆破参数选择不当、装药堵塞不按设计要求施工、人为操作失误等。重点探讨控制硐室大爆破飞石应采取的措施,并以湖北郧西30万方级配石料开采硐室大爆破为例,证明应用这些安全措施,成功地将爆破飞石控制在200m的范围之内。

The measures of controlling the flyrock in the coyote blasting are discussed. The problem of the flyrock in the coyote blasting is affected by the measurement, the geological condition, the arrangement of the coyote hole,the parameters of the coyote blasting,the charging and the plugging ,etc.
