空气间隔径向不耦合装药条件下柱状药包的破岩机理研究

Theory Research of Powder Destroying with Cylinder Charge in Rock under the conditon of Air Interval Decoupling Charge along Diameter

从空气间隔径向不耦合装药条件下岩石破坏机理方面入手,通过对冲击波、应力波的能量和爆生气体膨胀的能量利用的研究,分析空气间隔不耦合装药爆破的特点,进一步研究因不耦合系数不同,影响岩石裂隙区裂纹总长和平均长度的决定性因素,并由此推导出了炸药周围空气层"储能"的计算公式。

From the condition of air interval decoupling charge along diameter,research failure theory of rock.By aspect using power of shock wave、stress wave and detonation gases,analyze trait using blasting of air interval decoupling charge;on second thoughts,for difference of decoupling coefficient,affect determinative factor of total length and average length of crack in rock crack zone.Furthermore,deduce expressions of depositing energy by air around powder.In this way,more supply and develop the theory of decoupling charge along diameter in factual engineering.
