摘要
讨论了压力减敏与药包间距之间的关系,建立了减敏程度与药包间距关系的理想化模型.针对实际情况提出并深入讨论了药包的临界压死距离和临界减敏距离两个概念.用这两个概念来描述压力减敏与药包间距之间的关系更加合理,可以加深对炸药的压力减敏现象的认识,有助于毫秒爆破炮孔参数设计.
The space between blast-holes is the main factor influencing on the desensitization of industrial explosives. The relation of pressure desensitization to the space between explosive charges was analyzed and ideally modeled. Two concepts of critical dead-pressing space and critical desensitization space were introduced and discussed based on the practice and it is reasonable to depict the relation by the two concepts. It is shown that the two concepts are helpful for understanding the desensitization of explosives and guidable to design blasting holes in millisecond blasting.
