摘要
对矿井粉尘运移规律性进行了较系统的测定与研究.采用滤膜称重法测定粉尘浓度;样品经过液相分散法处理后,采用显微镜观察法测定粉尘的分散度,并利用数码相机和图像处理软件对计数工作进行改进.通过对测定的数据进行分析和归纳,得出了巷道沿程及断面上的粉尘浓度及分散度的分布规律.
The law of motion of the dust was studied.After the dust samples were treated by liquid-dispersed,the dust concentration was measured using the filter membrane-weighed method and the particle sizes of the dust were measured by the microscope method.The sample photos were taken by digital camera and further processed by image-processing software for the count,but these two methods were improved in the experiment.The distribution laws of concentration and particle size of the dust were obtained by summarizing and analyzing the data.
