本文采用摄影方法在海州露天煤矿对台阶爆破破碎块度进行了测量。根据现场试验所获得的数据,通过多元曲线拟合处理,给出了二种岩石爆破破碎块度的分布规律。所得结论对控制和提高爆破破碎质量具有重要意义。
In this paper, photographic method was used to measure the height of the block blasting in Haizhou opencast mine. According to the data obtained from the field test, the distribution rules of the two kinds of rock blasting fragmentation degree are given through the multivariate curve fitting process. The conclusions obtained are of great significance for controlling and improving the quality of blasting and crushing.
