Embodiment Construction

[0012] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0013] The coal rock fissure development infrared radiation monitoring test method of the present invention comprises utilizing rock press 1, infrared thermal imager 5, computer 6, and the concrete steps of test are as follows:

[0014] a. Close the doors and windows of the laboratory before the start of the test to prevent the influence of outdoor infrared radiation energy on the test environment;

[0015] b. On both sides of the workbench 8 of the rock press 1, respectively set the supports 2 for placing the coal rock test blocks. Set on the workbench 8 and the support 2, one coal-rock test block set on the workbench 8 is the loaded coal-rock test block 7, and the two coal-rock test blocks set on the support are the reference coal-rock test block 3. Use the baffle plate 4 to separate the loaded coal and rock test block 7 from the reference coal and rock ...

Abstract

The invention discloses a coal rock fracture development infrared radiation monitoring test method which is suitable for a coal rock fracture development infrared radiation monitoring test for researching a coal rock deformation condition of a mine. Supports for arranging coal rock test blocks are respectively arranged on two sides of a workbench of a rock press; three prepared coal rock test blocks are respectively arranged on the workbench and the supports; the rock press applies pressure on the loaded coal rock test blocks according to set pressure and set speed; a computer is used for processing infrared radiation mean temperature data of the loaded coal rock test blocks and a reference coal rock test block so as to obtain real infrared radiation data required by coal rock fracture development. The shortcoming of high environment and background factor influence on the conventional coal rock test block loading destroy infrared radiation monitoring test is overcome; an error caused by test conditions and the environment is reduced, the accuracy, the scientificity and the effectiveness of a test result are greatly improved, and instruction significance for the coal rock test block infrared radiation monitoring test is realized.

Description

technical field [0001] The invention relates to an infrared radiation monitoring test method, in particular to an infrared radiation monitoring test method suitable for studying coal rock deformation in mines, and belongs to the field of infrared remote sensing-rock mechanics. Background technique [0002] Mine coal pillar bearing and its yield failure, mine rock burst, coal burst, coal rock and gas outburst, roof movement, etc., are all dynamic processes under the joint action of ground stress and mining stress. When they move and deform, they are bound to be accompanied by the adjustment of the internal structure of the diagenetic material and certain physical and chemical phenomena, including internal damage, resistivity change, energy accumulation, dissipation, conversion and electronic transition, etc., such as the conversion of a part of mechanical energy into thermal energy. , and manifested in the form of infrared radiation. [0003] Since the early 1990s, in order ...
