A NEW DEVICE FOR DETERMINING THE STATIC AND DYNAMIC HARDNESS OF ROCKS UNDER HIGH HYDROSTATIC AND ROCK PRESSURE,
Abstract
The high pressures encountered during drilling of deep wells have a significant effect on the physicomechanical properties of the rocks. In this paper, the authors propose a new device, in which the desired static and/or dynamic loads are generated by mechanical means (a 60-ton hydraulic press). Additional static and/or dynamic pressures are generated at the upper end of the device by a 4-ton hydraulic press. The hydrostatic pressure is modeled by a pressure collar punch and 500,000 m thick rubber lining. The device is theoretically capable of producing pressures in excess of 10,000 atm. (Author)
