Mining activities and associated actions cause land-use/land-cover (LULC) changes across the world. The objective of this study were to evaluate historical impacts mining on surface biophysical characteristics, for first time, predict future in pattern vegetation cover land temperature (LST). In terms utilized data, satellite images Landsat, meteorological data Sungun mine Iran, Athabasca oil s...
The termination of mining activities often results in post-mining problems and risks. One these issues is the flooding mines. Long-term Ostrava Petrvald sub-basins Upper Silesian Coal Basin finished 1994. Tens coal seams were mined here, depth reached more than 1000 m below surface. Flooding sub-basin started flooded from one half only to prevent water into Karvina sub-basin, where continued. c...
Reservoir pore characteristics are an important part of shale gas reservoir capacity evaluation. Compared with Marine shale, the study coal measure is relatively backward in China. In order to deeply analyze properties and give priority favorable reservoirs, structure measures from Shanxi Formation Lower Permian Huainan Coalfield China were investigated this study. The size distribution, specif...
The Knothe time function is a classical method in predicting the ground mining subsidence. Nevertheless, it does not take observation data into account prediction process. Kalman filter can solve this issue at large extent. Taking coal work face of Xishan Coalfield as an example, research compares performance traditional and that improved by using method. comparison results show through improve...
