工程爆破对环境与生态的负面影响
negative effects of engineering blasting on the environment and ecology
影响爆破行为的岩体特性描写的最少、包括非连续面的密度、强度、硬度、频率及自然属性、而且对爆破区域内这些参数的可变性了解的也最少
The minimum description of rock mass properties that influence blast performance includes the density, strength, stiffness and frequency and nature of discontinuities, together with an understanding of the variability of these parameters across the blasting area
由于膨胀气体挤压这种物质、致使能量损失速度快、爆后产物的压力和温度迅速下降。这些损失作为膨胀波传到反应区之内、因而降低了压力和反应速率、且最终消除了对爆震波面传播的能量支持
As the expanding gases compress such material, energy is lost rapidly and pressure and temperature drop sharply in the reaction products. These losses are communicated to the interior of the reaction zone as a rarefaction wave, lowering the pressure and reaction rate, and ultimately removing support far the propagation of the detonation front
