【Abstract】 The scopes and characteristics of rock mechanics at great depth are discussed. This paper introduces the full-scale drilling system,the measurement of geo-stresses,rock fracture toughness,static and dynamic rock parameters,the advances in techniques of well-bore stability prediction and measurement during drilling,and physical and numerical simulations of hydraulic fracturing,in China. The challenges facing rock mechanics at great depth and technical issues to be solved are presented.更多还原
