摘要
在利用成像技术检测岩石颗粒的破碎效果时,所选择的表征参数是影响结果的重要因素。基于图像的检测系统由三部分组成:图像采集系统、存储平台和数字图像处理系统。分别分析了加载方式和给料粒度对岩石破碎程度和破碎后岩石形态特征的影响;分析了灰岩、灰岩和花岗岩在剪切和挤压载荷作用下的破碎比和成砂比。实验结果表明,在剪切压缩载荷作用下,破碎比和成砂率对不同材料组成的岩石的破碎起关键作用。对进料粒度为9.5 mm ~ 16mm时的破碎效果分析表明,边角、圆度与整体轮廓之间存在较大的相关性。为智能矿山建设和设备优化的后续研究提供了依据,值得进一步推广应用。
Parameter selection and experimental study of the rock particle crushing effect using an image-based method
When maging is used to detect the crushing effect of rock particles, the selected characterization parameters are important factors affecting the results. The image-based detection system is composed of three parts: an image acquisition system, a storage platform, and a digital image processing system.The influence of loading mode and feeding particle size on rock crushing degree and rock morphology characteristics after crushing are analyzed respectively; The crushing ratio and sand-forming ratio of limestone, limestone and granite under shear and extrusion loads are analyzed. The experimental results show that the crushing ratio and sand formation rate play a key role in the crushing of rocks composed of different materials under shear compression loading. The effect analysis of crushing under the feed particle size of 9.5 mm to 16mm shows that there is a great correlation between edges and corners, roundness and overall contour. It provides a basis for the follow-up research on intelligent mine construction and equipment optimization, and is worthy of further popularization and application.
期刊介绍:
International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
