Laws of propagation and attenuation of spherical stress wave in the geologic media have been studied in detail by means of mini - chemical explosion test in laboratory in this paper . the lows are fundamental to improve and develop theoretic models for underground explosions ( tamped and cavity decoupled ) on the stress wave propagation , safety and containment during the explosion 运用微型药量化爆模拟试验可以比较深入、细致地研究地质介质中球形发散应力波的传播、衰减规律,这对于改进、发展用于估算地下爆炸(填实和空腔解耦)应力波的传播及安全封闭的理论计算模型是至关重要的基础资料。
