The Application of Image Processing Techniques in Rock Blasting Fragmentation Analysis

图像处理技术在岩石爆破块度分析中的应用

This method takes full advantage of the low tensile strength of rock and high permeating ability of high pressure water which enable the initiation and propagation of cracks and the accomplishment of rock fragmentation.

本方法充分运用了岩石抗拉强度低，和高压水对岩石有利渗透作用的条件，从而达到岩石裂纹的产生与扩展，直到最后劈裂。

Recent Development in Assessing Fragmentation of Rock Blasting Experimental Research on Thermal Peel Fragmentation of Rock

爆堆块度评价方法研究的进展热力剥离破碎岩石试验

If the rock is homogeneous, the large size fragmentation can generally be attained more easily.

如果是均质岩石, 一般可以比较容易地爆出大块料石.

Three jet stages in the flow structure and the rock fragmentation mechanism of strike, impact, water wedge, cavitations erosion, cutting of water jet, and the course of rock fragmentation, are analyzed.

分析了水射流流动结构中存在的三个射流阶段和水射流作用于煤层时所具有的撞击、冲击、水楔、气蚀、剪切等破岩机理和岩石的破坏过程。
