INFRARED RADIATION QUANTITATIVE CHARACTERIZATION METHOD FOR DAMAGE EVOLUTION OF COAL-BEARING ROCKS

摘要

Disclosed in the present invention is a infrared radiation quantitative characterization method for the damage evolution of coal-bearing rocks. In the present method, the maximum value of an infrared radiation temperature change matrix of coal rocks is referred to as a threshold value for infrared radiation change of the coal-bearing rock due to microelement damage. The cumulative count of infrared radiation during the damage evolution process of the coal-bearing rock is screened. The infrared radiation quantitative characterization method for the damage evolution of coal-bearing rocks is constructed on the basis of the theory of continuous damage mechanics. By means of monitoring infrared radiation data in real time, the real-time process of the damage evolution of coal rock masses may be dynamically and accurately evaluated, which thereby improves mine safety production levels, and improves the stability and accuracy of coal rock mass monitoring in the field of modern rock mechanics and engineering.
