| THE USE OF HIGH MODULUS INCLUSION FOR IN-SITU STRESS DETERMINATION IN VISCO-ELASTIC ROCKS, |
MAR 1968 |
|
| Authors:
Naamen Peleg; MINNESOTA UNIV MINNEAPOLIS SCHOOL OF MINERAL AND METALLURGICAL ENGINEERING
|
 | Experiments have been conducted to determine the possible use of a high modulus inclusion for the direct determination of stresses in a visco-elastic material. A system was designed to sustain a constant hydrostatic pressure over a long period of time--the main feature of this system is a pressure intensifier activated and regulated by gas pressure. Two sets of tests were conducted with an inclusion inserted in a hole drilled in ... |

Elmer White; CALIFORNIA UNIV LIVERMORE RADIATION LAB
|
| An investigation of the minimum power required for retorting oil shale in situ using the thermal heat from a nuclear reactor revealed the necessity of having a 340 MW reactor. In order to map temperature profiles in a nuclear chimney, a new equation was derived which computes the ratio of the solid-to-fluid temperature. Heat exchangers and pumping power requirements were established for the model under ... |

| Analogies between nuclear and conventional excavations are developed from a tabulation of data from 153 mine, quarry, roadway, and dam excavations. The following factors were used as the basis for tabulation of conventional excavation data: purpose, location, precipitation, temperature, ground water level, lithology, mass strength, structural pattern, slope plan, slope profile, depth of excavation, slope height, average inclination, and stability. It was found that ... |

| Some computational aspects of the Mathematical Programming Model for Optimum Design of Open Pit Ore Mines which has been described in Management Sciences Research Report No. 92 are explored. A small pilot problem reveals the possibilities for finding a removed extreme point which always allows for straightforward use of the simplex method in order to reach the global optimum of the one ore vein problem. It is further shown that ... |

| It is shown that there exists a nonlinear function linking the direct operating profits (= proceeds from the sale of ore minus direct operating cost of extraction, transportation, and upgrading) to the shape and depth of an open pit ore mine. This gives rise to the question of how to find the overall maximum of the function. In this paper it is described how the maximum can be determined by ... |

|
| This is an overall study of the whole process of projectile penetration into soil. The governing differential equations for the soil target medium are developed using the equations of motion and the continuity condition. Constitutive relationships are derived from Mohr-Coulomb theory for a rigid plastic material and from viscosity theory. The other necessary equations are generated from an experimental investigation of the penetration mechanism. |

| For studying the propagation of VLF waves in rock, an excursion to German and Dutch mines was made in September 1963. It was the purpose of this excursion to conduct measurements of subsurface propagation through geological bodies which in their structure and in the type of disturbances (mineralization) differed considerably from the regions of Tyrolian mines studied so far. |

| Whether it be in the scope of activities, the rise of the technological level or the increase in actual prospecting effectiveness, the development of Geophysical work in China has been unusually rapid during the past decade. The revival by the socialist regime of New China of a scientific technique almost forgotten by Old China amply demonstrates the party's and Government's interest in and support of scientific technology.
