Thus accurate assessment of elastic properties of coal rocks is extremely important for ground mining.展开更多

文摘1 Introduction Mechanical properties of coal are most important parameters in controlling fluid storage and flow before and after coal extraction [1-2].Reservoir simulation design and wellbore stability analysis are influenced by elastic and strength character of coal rocks[3].Young's modulus, and shear modulus are usedwhen deformations in underground mines need to be computed. Thus accurate assessment of elastic properties of coal rocks is extremely important for ground mining.
