To investigate the mechanical evolution progress of mining-induced pressure-relief gas migration channel in overlying strata fissure at fully mechanized mining working face, physical similarity simulation tests were conducted to experimentally and numerically evaluate the mining process of a coal mine in Heshun, Shanxi Province. The profiles of the...

Shaft friction is an important component of the pile foundation bearing capacity in construction projects, whereas the roughness of a pile–rock interface is one of the key components affecting shaft friction. An accurate characterization of the roughness of a pile–rock interface can help in determining the lateral friction of the pile–rock interfac...

The classical densification geodetic networks, the permanent or the fundamental densification GPS/GNSS networks, and the deformation monitoring networks must provide the precision and reliability requirements. These networks should also be able to detect the possible earth crust movements. In designed densification networks, if the total observatio...

In order to more accurately understand the stability of shield operation in expansive geotechnical environments. In this study, the stability of shield operation in expansive geotechnical environment is studied by ABAQUS software model construction and numerical simulation. The results show that when the support force ratio is lower than 0.2, the s...

The interrelation of essential nutrients in soils and crops has been established. However, studies investigating the influence of selected properties of soils on the bioavailability of trace elements to cereals crops are scanty. For this purpose, soil samples were randomly collected from selected ten cultivated fields. Relevant soil properties and ...
