爆炸挤压成井药量计算研究

Calculation Method for Explosive Charges in Formation of Shaft by Blasting Compaction

从条形装药爆破成井机理出发 ,建立了爆炸挤压成井弹塑性模型。利用鲍姆状态方程和质量守恒定律 ,给出了爆炸挤压成井药量计算公式。进行了现场实验 ,对试验数据和计算结果进行了对比 ,吻合性好。新计算方法为爆炸成井炸药量的计算提供了理论方法。

Based on mechanism of shaft forming by blasting with linear charges, an elastic-plastic model of shaft forming by blasting compaction is established. According to the state equation and the mass conservation law, the authors provide a formula for calculating explosive charges in shaft forming by blasting compaction. The field tests were carried out and their results were compared with their calculated results. Both of them are very correspondent. A new method is provided for calculating explosive charges of shaft forming by blasting compaction.
