Title:
METHOD FOR INFRARED RADIATION MONITORING TESTS OF COAL ROCK FRACTURE DEVELOPMENT
Document Type and Number:
WIPO Patent Application WO/2015/176615
Kind Code:
A1
Abstract:
A method for experiments to monitor coal rock fracture development using infrared radiation monitoring, for use in experiments using infrared radiation in monitoring coal rock fracture development for the study of coal rock deformation in mines. Supports (2) for placing coal rock test blocks (3) are respectively arranged on two sides of a worktable (8) of a rock press (1). Three prepared coal rock test blocks (3) are respectively arranged on the worktable (8) and the supports (2). The rock press (1) presses the loaded coal rock test blocks (3) according to a set pressure and speed. A computer (6) processes infrared radiation average temperature data of a loaded coal rock test block (7) and reference coal rock test blocks (3), and required real infrared radiation data of coal rock fracture development is obtained. The method overcomes the shortcomings of large environmental and background factor influences in previous infrared radiation monitoring tests of coal rock test block loaded damage, thereby reducing errors caused by the test conditions and environment, and significantly improving the accuracy, scientific nature and effectiveness of the test results. The present invention has guiding significance for infrared radiation monitoring tests of coal rock test blocks.
