Deformation Analysis of Bending Stratum Based on Displacement Function Method

Geotechnical and Geological Engineering, 2020
Bending strata is an inevitable consequence of coal mining, which will waste mineral resources and influence their production. In this paper, the displacement function suitable for curved beam in polar coordinates is introduced, and the partial differential governing equation of curved beam is obtained by theoretical analysis.

Deformation Movement of Hugely-Thick Conglomerate Stratum in Longwall Top Coal Caving

Geotechnical and Geological Engineering, 2021
In the process of longwall top coal caving, the deformation and movement of the overlying hugely-thick conglomerate stratum (HTCS) directly affects the rock pressure behavior in the longwall. Based on conditions of the geology and mining of coal face 13,180 at Gengcun coal mine of Yima Mining Area, China, numerical and similar material simulations were

Structure and Function of Human Stratum corneum under Deformation

Dermatology, 2002
<i>Background:</i> The stratum corneum (SC) has an important barrier function. The effect of a mechanical stress applied to the SC is controversial on this important physiological parameter. <i>Objective and Methods:</i> To assess both in vitro and in vivo the structure and function of human SC submitted to controlled strains ...

Analysis on the Gravel Stratum Deformation by Dewatering

Key Engineering Materials, 2007
Large particle-size, shallow groundwater level, and large permeate coefficient are the characteristics of gravel stratum, which may results in large ground deformation. Ground deformation depends on several factors. Using the RFPA2D-Flow software exploited by the Center for Rock Instability and Seismic Research of Northeastern University (CRISR), the ...

Field Measurement Research on Overburden Stratum Movement and Deformation

Applied Mechanics and Materials, 2012
According to field measurement datum in disturbed overburden stratum of five drillings, disturbed overburden stratum movement characteristics were analyzed. Negative exponent function model of measurement points movement law was also constructed. Moreover, variation law of stratum subsidence speed and relation between overburden stratum subsidence ...
