岩石深孔梯段爆破侧向破裂范围计算分析探讨

Calculation and Analysis of Lateral Splitting Scope of Rock Deephole Bench Blasting

根据爆炸气体等熵膨胀理论和应力波传播理论,推导了孔壁压力计算公式,以及由应力波传播和爆炸气体引起应力状态的计算公式。同时根据现场实际资料,进行了混装乳化炸药在岩石深孔梯段爆破中的侧向破裂范围的实际计算,计算结果对实际工程有一定的参考应用价值.

On the basis of the equi-entropy expansion theory and stress wave propagation theory of explosive gas, calculation formulae of pressure on the hole wall and pressure force state caused by stress wave and explosive gas are deduced. Combining with the practical data, the lateral splitting scope of rock deephole bench blasting using the mix-load emulsion explosives is calculated. It has a practical value in practical engineerings.
