Mechanism of mining-induced slope movement for gullies overlaying shallow coal seams
Journal of Mountain Science, 2013This paper provides an improved understanding of the movement mechanisms of both bed-rock gully and sandy soil gully when underground mining occurs underneath, followed by systematic analysis of the contributing factors such as mining advance direction, gully slope angle, gully erosion coefficient and mining height. This paper presents the results from

Mathematical and Experimental Simulation of Hydraulic Fracturing in Shallow Coal Seams
SPE Eastern Regional Meeting, 1991ABSTRACT Laboratory hydraulic fracturing experiments on unconfined coal blocks were conducted to simulate fracture stimulation of shallow coal seams. Fractures were initiated by injecting a gelled water into an openhole section of a wellbore. Multiple fractures appeared at the sample periphery during injection period.

Premine study of shallow coal seams using highâresolution seismic reflection methods
GEOPHYSICS, 1991Geological investigations in the Illinois Basin coalfields have shown that significant differences in safe and economical exploitation of coal depends directly on accurate mapping of the roof rock overlying the seam, as well as on geological structures in the coal measures. In roof rock transition zones above the Herrin (No.

Fracture Zonation for Overlying Strata in Underground Mining of Shallow Coal Seam
Advanced Materials Research, 2012Overburden fractures are the passageways for water resource loss in underground mining. A new zonation for overburden movement was present through the analysis on hydraulic aperture and permeability according to numerical calculations. Fractured zone was divided into three parts, the upper, the middle and the lower and their heights were educed. In the

Investigation of movement and damage of integral overburden during shallow coal seam mining
International Journal of Rock Mechanics and Mining Sciences, 2019Abstract Most prediction methods used to calculate mining-induced subsidence are empirical, which cannot explain the mechanism of fundamental rock strata movement. In this paper, based on key stratum theory and the mechanical analysis of overburden, a new analytical solution, the Analogous Hyperbola Subsidence Model (AHSM), was proposed to describe ...

Study on water resisting property of subsurface aquiclude in shallow coal seam mining
Journal of Coal Science and Engineering (China), 2008According to the characteristic of clay aquiclude of overburden, the proper simulation materials and proportions of mixture for simulating the plastic clay aquiclude layers were developed, and the plastic similarity conditions were setup. Thus, the similitude and simulation method in whole stress-strain was progressed.
