Abstract In order to study the creep deformation characteristics of coal rock in Daping Mine, the uniaxial and triaxial creep tests of coal samples were carried out by HSW-200R manual triaxial creep tester. According to the test data, the constitutive equation was obtained by using origin software for linear regression, and the creep parameters of the constitutive equation were identified. The results showed that the creep characteristics of coal and rock in the Taiping Mine could be well described by using the accelerated model of the western origin. The test method exerted some referential significance for the research of similar coal-rock creep.
