Relationship of roof falls in underground coal mines to fractures mapped on ERTS-1 imagery [PDF]

ERTS imagery is of unique value for mapping of certain fractures that are not identifiable on aircraft imagery. Because color infrared and ERTS imagery complement each other both sources of data were used to map fractures in western Indiana and eastern ...

Stress Redistribution Mechanisms and Subsidence Control of Fluidized Gangue Backfilling in Underground Coal Mining: Integrated Experimental and Numerical Investigation

Energy Science &Engineering, EarlyView.
Fluidized gangue backfilling controls mining subsidence through stress redistribution in composite backfill‐pillar systems, reducing surface settlement and stress concentrations. Multi‐scale experimental and numerical analysis provides quantitative design parameters for optimizing ground control in sustainable underground coal mining operations ...

Subsidence characteristics of mining affected boundary area and modified surface subsidence prediction model under thick unconsolidated layer

Meitan xuebao
When the upper part of coal-bearing strata is covered by the thick unconsolidated layer, the boundary area of the subsidence basin induced by coal mining exhibits a distinctive phenomenon of range expansion and slow convergence.

Study on Damage Characteristics and Evolution Law of Macro‐Meso Structure of Surrounding Rock Under Mining Stress

Energy Science &Engineering, EarlyView.
Investigating the differential impact of mining stress on roadways, we find that in horizontally stressed environments, the inner surrounding rock exhibits more pronounced macro‐meso damage compared to the outer side. ABSTRACT The control of surrounding rocks in dynamic pressure roadways has consistently been one of the challenging predicaments in the ...

New Boundary Element Method For Analysis Of Surface Subsidence Due To Coal Mining [PDF]

, 2014
Rock and coal in coal bearing formation belong to layered sedimentary rocks. Their large-scale subsidence may occur because of coal mining. Thus, it is one of research highlights to develop an analytical tool suitable for these layered rocks.

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,
