Study of Thermo-Rheology Characters of Rock under the Uni-Axial Compression

Abstract

This paper introduces temperature effect to rock model. It sets up a thermo-visco-elastic-plastic rock model. Based on the rock model which consists of spring, dashpot and plastic elements under the condition of un-axial compression, the behaviors of the thermo-visco-elastic-plastic in rock are discussed, and the equations of the constitutive, creep, unload and relaxation have been obtained. This model can reflect the rock or rock mass average thermo-rheology character. Meanwhile, this study gives a explanation of the significances of this kind of model in the practical use.

Study on the Structure Model and Controlling Method of Subsidence in Flat Seam and Deep Mining

“…Numbers studies have been undertaken to explain the related law of stratum movement and surface subsidence [1,2,3] . In the study of the ground subsidence in flat seam and deep mining, we set up the corresponding structure subsidence model, and analyzed its influencing factors.…”
