Physical and theoretical modeling of rock slopes against block-flexure toppling failure
Block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. In such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. In this paper, first, a brief review of previous studies on toppling failures is presented. Then, the physical and mechanical properties of experimental mode...
متن کاملبررسی بهبود دهندههای مختلف بر روی خصوصیات سنگهای ضعیف
In accordance with development of coastal area around the worlds, constructing breakwaters with sophisticated materials is increased. In the south costs of Iran, rock mass breakwaters is more common than other types of breakwaters. However enough source of good rock deposits is quite rare. In that region, Lomashel rock is the dominant rock formation. Therefore using different coating materials ...
متن کاملA Physical-based Model of Permeability/Porosity Relationship for the Rock Data of Iran Southern Carbonate Reservoirs
The prediction of porosity is achieved by using available core and log data; however, the estimation of permeability is limited to the scare core data. Hence, porosity and saturation data through the framework of flow units can be used to make an estimation of reservoir permeability. The purpose of this study is to predict the permeability of a carbonate gas reservoir by using physical-based em...
متن کاملA closer look at rock physics models and their assisted interpretation in seismic exploration
Subsurface rocks and their fluid content along with their architecture affect reflected seismic waves through variations in their travel time, reflection amplitude, and phase within the field of exploration seismology. The combined effects of these factors make subsurface interpretation by using reflection waves very difficult. Therefore, assistance from other subsurface disciplines is needed i...
متن کاملA laboratory study of rock properties affecting the penetration rate of pneumatic top hammer drills
In this paper, after collecting the rock samples from eight mines and one high way slope, the tests for determination of dry density, Uniaxial Compressive Strength, tensile Strength (Brazilian Test), elastic modulus, Schmidt hammer rebound number have been done on samples. In addition, in order to calculating the mean size of rock grains, quartz content, hardness and abrasivity, a thin sections...
متن کاملPhysical Model Test and Numerical Simulation Study of Deformation Mechanism of Wall Rock on Open Pit to Underground Mining (RESEARCH NOTE)
This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...
