【摘要】 前沿抛距是抛掷堆积计算的关键,而抛掷堆积计算又是定向爆破设计的核心。为了更加准确、客观地计算定向爆破前沿抛距,通过设计不同的爆破参数、布药结构,进行大量现场模拟试验,总结并分析抛掷堆积规律,找到影响定向爆破前沿抛距的主要因素,进一步完善前沿抛距计算方法,更好地指导定向爆破设计与施工。更多还原

【Abstract】 The front casting distance is the key to the throw pile calculation which is the core of directional blasting design.In order to calculate the front casting distance exactly and objectively,a series of field simulation tests have been conducted by blasting parameters and layout of charge,thus dominant factors of the throw pile law have been discovered that are useful to deepening and improving the method of front casting distance calculation,which could serve as a better guide to the directional blasting of damp construction.更多还原
