摘要:
为将具有高精度、非接触性和全场观测等优点的数字散斑技术应用到煤矿相似模拟实验中，完成裂隙发育、应力变形和上覆岩层位移分析，介绍数字散斑的基本原理、相关系数和搜索方式等关键性环节，并利用MATLAB建立实用性强的数字散斑软件系统、硬件测量系统和像素位移转化系统，并进行图像二值化处理。结果表明：在利用数字散斑分析方法对煤层开挖过程中的覆岩下沉量进行定量分析时，不仅方便快捷，而且误差较小，证明数字散斑在相似模拟实验中具有较高的可靠度。这将在一定程度上促进数字散斑技术在煤矿领域的实际应用。
Abstract:
In order to apply the digital speckle technology,which has the advantages of high precision,noncontact,fullfield observation and so on,to the similar simulation test of coal mine,the analysis of fracture development,stress deformation and overburden displacement was completed.The basic principle,correlation coefficient,search mode and other key links of digital speckle were introduced,and the MATLAB was used to establish the practical digital speckle software system,hardware measurement system and pixel displacement conversion system,and the image binarization processing was conducted.The results showed that when using the digital speckle analysis method to carry out the quantitative analysis of overburden subsidence during the coal seam excavation,it was not only convenient and quick,but also had a small error,which proved that the digital speckle had high reliability in the similar simulation test.The results will promote the practical application of digital speckle technology in the field of coal mine to a certain extent.
