Modeling and Simulation of Deformation Mechanism of

The existence of coal mine water has an important influence on the instability of soft rock roadway in mining engineering. Considering the effect of mine water, a case study on the fracture mechanism and control technology of soft rock roadway was performed in this paper. The results showed that with the increase of moisture content, the uniaxial compressive strength of mudstone nonlinearly ...

2019-8-5  Major global events during the Oligocene epoch included a climatic change from warm “greenhouse” to a cooler “icehouse” that was accompanied by the onset of Antarctic glaciation. These events led to decline in water temperature, salinity, nutrient supply and oxygen levels, and the extinction of some major fauna and flora. Within the study area, during this epoch, the shrinkage of the ...

2010-5-11  The end-Permian mass extinction horizon is marked by an abrupt shift in style of carbonate sedimentation and a negative excursion in the carbon isotope ( δ 13C) composition of carbonate minerals. Several extinction scenarios consistent with these observations have been put forward. Secular variation in the calcium isotope ( δ 44/40Ca) composition of marine sediments provides a tool for ...

US7869565B2 - Classification method for sedimentary

A method of determining a parameter of interest of reservoir rock formation is described using the steps of measuring an x-ray attenuation or absorption distribution of a sample of said rock formation, identifying the mineral phase part of said distribution, and subdividing the mineral phase part of said distribution to derive classification or rock type information of said sample.
