Evaluation of the energy efficiency of rotary percussive drilling using dimensionless energy index
文献摘要：
This paper sets forth a geomechanics framework for assessing the energy efficiency of rotary percussive drilling using the energy criterion,which has been proposed by Victor Oparin for volumetric destruction of high-stress rocks having nonuniform physico-mechanical properties.We review the long-term research and development in the specified area of science and technology,including research and development projects implemented at the Institute of Mining,Siberian Branch of the Russian Academy of Sciences.A new modified expression of Oparin's dimensionless energy criterion of volumetric rock destruction k is introduced.The range of in situ values is determined for the energy criterion of volu-metric rock destruction at the optimized energy efficiency of rotary percussive drilling.The temporo-spatial intervals of geotechnical monitoring are found to control pneumatic drilling energy efficiency at subsoil use objects in Russia.The integrated experimental,theoretical and geotechnical approach to the comprehensive investigation of real-time processes of rock fracture in rotary percussive drilling using the energy concept possesses the necessary geomechanical performance-and-technology potential to create the next level geotechnical monitoring of drilling systems for various purposes,including deter-mination of physico-mechanical properties and the stress-strain analysis of rock mass in full-scale drilling.
