摘要(Abstract)：

在硐室爆破工程实践中,为了达到设计的抛掷距离和特定的抛体堆积形态,往往设计布置平面药包。本文通过现场小型模拟试验,对平面药包的爆破漏斗大小与深度、抛掷堆积规律以及合适的药包间、排距进行了系统研究与分析。模拟试验证明,抛掷距离与最小抵抗线成正比关系;群药包爆破时,抛掷距离与药包的间、排距也有一定关系。
In order to achieving a designed throwing distance or special shape of pile in practical chamber blasting, the plane charges were, sometimes,adopted. By small-scale simulating tests in a field, the size and depth of blasting cone from plane charges, the thrown piling and reasonable spacing and inter-row distances of charges were systemically studied. The simulating tests prove that a throwing distance is in direct proportion to charge's burden and has certain relation to the spacing and inter-row distances of charges.
