Özet

Drillholes which are full of water are always a great problem for blasting efficiency. Water brings out the problem of inefficient usage of explosive energy. In watery rock mass, Heavy ANFO, emulsion or slurry type explosives are used instead of conventional ANFO. In the quarries operated nearby Istanbul, water in rock mass is affecting the blasting efficiency in a negative way. So the particle size distribution is coarser than expected and amount of big blocks in muckpile is high. In the studied quarry Heavy ANFO is applied to use explosive energy properly. In the quarry, different blasts carried out using ANFO and Heavy ANFO are investigated. These blasts are evaluated in terms of the blasting techniques and the results are compared. During the evaluation of blasting results, visual analysis is done pre-blast and after blast, but also image analysis software is used. The discontinuity properties of benches are evaluated by image processing software before blasting. The image analysis software which is used for evaluation of discontinuities determines the in-situ block size, joint frequency and orientation. After blasting, image processing software is used to determine the particle size distribution.
