本文根据我国定向爆破工程技术资料,认为应用抛掷初速度及弹道理论来计算抛距时,必须考虑空气阻力的作用,提出一套定向爆破抛距计算公式。文中进行了工程实例的验算,比较接近实际。本计算方法更能适用于大药包抛距计算。 According to the technical data of directional blasting engineering in China, we think that when using the initial velocity of throwing and ballistic theory to calculate the throw distance, we must consider the effect of air resistance and put forward a set of directional blasting throw distance calculation formula. The article carried out the checking of engineering examples, more realistic. The calculation method is more suitable for large bag throw distance calculation.
