IInfiltration rate and hydraulic conductivity are immensely important parameters for evaluating the hydrology of subsurface environments. Specifically, in disposal wells schemes and in artificial recharge plans both properties must be correctly assessed to better analyze the performance of these installations. In a new research, tanker water and rainfall runoff were injected into a 22.5 m deep ...

Phosphogypsum is a byproduct of phosphate fertilizer production, and more than 700 million metric tons have accumulated on 2,500 ha in Florida. Field research was conducted to compare the benefits of capping phosphogypsum with overburden (up to 15 cm in depth) from mined sites versus treatment of the phosphogypsum with minimal amendments. After four growing seasons, vegetation cover was excelle...

Through-the-Earth (TTE) communication systems require minimal infrastructure to operate. Hence, they are assumed to be more survivable and more conventional than other underground mine communications systems. This survivability is a major advantage for TTE systems. In 2006, Congress passed the Mine Improvement and New Emergency Response Act (MINER Act), which requires all underground coal mines...

Plants regularly experience suboptimal environments, but this can be particularly acute on highly-disturbed mine sites. Two North American willows—Salix discolor Muhl. (DIS) and S. eriocephala Michx. (ERI)—were established in common-garden field tests on two adjacent coal mine spoil sites: one with high clay content, the other with shale overburden. The high clay content site had 44% less produ...

Overburden layers continue to be a problem for recording and analyzing information in seismic surveys. This study aims to examine the effects of overburden layers on seismic wave propagation and imaging. In the investigation, we look at the effect of low velocity, low density overburden on seismic imaging. To investigate this problem, a finite difference elastic wave modelling study was conduct...

The purpose of this study was to evaluate the large-scale structure, and hence available reserves, of the Lower Cretaceous Luscar Formation near Mountain Park, in the Foothills of Alberta. Coal resource evaluation clearly requires information on the mineable tonnages, as well as the grade, of the coal strata. In open pit mining, the volume of coal economically extracted from a seam is directly ...

Based on FBG fiber Bragg grating technology and BOTDA distributed optical fiber sensing technology, this study used fine sand to simulate overburden layer in vertical shaft model equipment. The placing technique and test method for optical fiber sensors in the overburden layer were studied, combined with MODFLOW software to simulate the change of the water head value when the overburden layer w...

The results on the research of heat-insulating porous ceramic materials produced using overburden rocks Novodvorsk deposit Pinsk district Brest region as main component raw are presented in study and use bulk rock consisting glauconite sands aleurites is recommended. Low-melting clay, basalt a blowing agent used additional components, rational combination which would ensure forming ability mass...

The present study evaluated the ground water quality and physico-chemical characteristics of the water samples collected from 15 bore wells in the study area which is situated in Rangappa Layout which is located in the Ittamadgu Village of Uttarahalli Hobli which falls in the Bangalore South taluk of the Bangalore Urban district. Physico-chemical characteristics of the collected water samples, ...
