摘要
为了精确提取扫描电镜图像微观渗透信息,以开滦林南仓矿和内蒙古酸刺沟矿岩芯制作的SEM照片为研究对象,针对每个样品拍摄了放大1 000倍的SEM照片,重点研究利用图像处理软件实现对同一尺度SEM图像信息的提取。最后建立微观参数与渗透率之间的数学模型,得出孔隙大小的划分标准,并经过实验验证。
In order to accurately extract microscopic permeability information of SEM image, the paper makes SEM photographs as the research objects which are collected from Linnan cang mine of Kailuan and Suancigou mine of Inner Mongolia, shot SEM photographs of 1 000 times in magnification for each sample, focusing on the information extraction of SEM images which are in the same scale with the use of image processing software. Finally, build mathematical models among area and perimeter of microscopic pore and permeability, obtaining the dividing standard, verified by experiments.
