TESTING STUDY ON THE CHARACTERISTICS OF CREEP AND DAMAGE OF COAL AND OTHER ROCKS
煤岩蠕变损伤特性的实验研究

The physic-mechanical characteristics of coal and other rocks are discussed based on the results of the mechanical testing, the microscopic structure analysis and the creeping tests. The respondent law of the deformation, damage and rupture of coal and other rocks under the loading is obtained. Finally, the method of checking deviator stress to consider the damage of coal and other rocks is proposed.
