摘要
从研究爆破应力波的远区传播机理和确定其破岩效应出发,介绍了爆炸应力波的传播及其破岩效应研究从简单到复杂、从理想化材料到尽可能与现实实际相吻合的材料、从近到远的研究历程,及其各阶段取得成果与不足。认为目前的研究已由过去尽量简化岩性(弹性均质体)和爆源(球状药包),向尽量反应炸药爆炸与装药结构特征、反应岩体现状与本性的方向发展;由以破岩为目的,向爆破后续的安全问题发展。并为研究爆破对保留岩体的影响及其稳定性,提出了今后应加强工作的具体意见。
After researching the mechanism of propagation of blast stress wave in remote area and determining the effect of rock fragmentation, the research history is introduced which is from uncomplicated to complex, from the ideal material to the material coincided with reality as far as possible and from the close to the remote area. The achievements in the research are introduced. The paper thinks that the present research is from the simplification of mass rock (elastic and homogeneous) and blasting source (globe explosive package) to the direction of representing the properties of explosive detonating, charging construction and natural character of mass rock, from the ends of rock fragmentation to the safety problem of blasting. In view of the stability of reserved rock under the blast, the detail advice for improving the research in future is suggested.
