Abstract

L'invention concerne un procédé pour un test de surveillance à rayonnement infrarouge du développement d'une fracture de roches charbonneuses, adapté à un test de surveillance à rayonnement infrarouge du développement d'une fracture de roches charbonneuses pour la déformation des roches dans des mines de charbon. Des supports (2) permettant de placer des blocs de test (3) de roches charbonneuses sont respectivement disposés sur deux côtés d'une table de travail (8) d'une presse de roche (1). Trois blocs de test (3) de roches charbonneuses sont respectivement disposés sur la table de travail (8) et les supports (2). La presse de roche (1) presse les blocs de test (3) de roches charbonneuses chargées en fonction d'une pression et d'une vitesse définies. Un ordinateur (6) traite des données de température moyenne d'un rayonnement infrarouge d'un bloc de test (7) de roches charbonneuses chargées et de blocs de test (3) de roches charbonneuses de référence, et des données de rayonnement infrarouge réelles requises d'un développement de fracture de roche charbonneuse sont obtenues. Le procédé permet de surmonter les problèmes des fortes influences de l'environnement et de l'arrière-plan des précédents tests de surveillance à rayonnement infrarouge de blocs de test de roches charbonneuses chargés endommagés, ce qui permet de réduire les erreurs provoquées par les conditions et l'environnement du test, et d'améliorer de manière significative la précision, la nature scientifique et l'efficacité des résultats du test. La présente invention guide significativement les tests de surveillance à rayonnement infrarouge de blocs de test de roches charbonneuses.
