铁铊控爆解体的装药量计算

CALCULATION OF CHARGE SIZE IN CONTROLLED FRAGMENTATIONAL BLASTING OF BULKY IRON LUMP

作者将钢铁冶炼厂的铁铊在控爆解体时所取得装药量与被爆体截面大小关系的原始数据,采用数理统计原理,进行回归分析后总结出装药量计算式,并在理论上作了方差分析。结果表明置信度高。据此,在实践上作了施爆,证明使用可靠、效果良好。

An equation to calculate the amount of explosive charge for controlled fragmentational blasting of bulky iron lump is established through processing field shooting data loss. By correlating the explosive amount with the cross section of the lump, and making regressional analysis along with variance analysis, it is found that the proposed equation gives mathematically acceptable reliability in terms of percent confidence. Blasting practice based on the equation also gives satisfactory fragmentation.
