Degradation mechanism of microstructure of residual coal pillars during highly mineralized mine-water storage in coal mine goaf

Underground Space
Driven by the “dual carbon” strategy, the functionality of coal mine underground reservoirs is transitioning toward multimedia collaborative storage, such as CO2 geological sequestration and strategic energy reserves.

Unravelling the relative contributions of climate change and ground disturbance to subsurface temperature perturbations: Case studies from Tyneside, UK [PDF]

, 2016
When assessing subsurface urban heat islands (UHIs) it is important to distinguish between localized effects of land-use change and the impacts of global climate change. However, few investigations have successfully unraveled the two influences.

Airflow stability and diagonal mine ventilation system optimization: a case study [PDF]

, 2018
Airflow reverse is a severe problem in an underground ventilation system. In addition, the airflow stability and safety production can be seriously affected by the problem of air velocity overrun in the roadways.

Theory and technical system of coal ecological open-pit mining and its application

Meitan xuebao
Large-scale open-pit coal mining will cause ecological problems such as land excavation and occupation, groundwater drainage, soil erosion, vegetation destruction, air pollution, and regional landscape damage. The selection of existing open-pit coal mine

The Miocene Bükkábrány Fossil Forest in Hungary – field observations and project outline [PDF]

, 2008
The oldest, standing forest preserved as wood has been found at Bükkábrány, Hungary. An open-pit mine working Upper Miocene (Pannonian) lignite revealed sixteen stumps, 1.8 to 3.6 m diameter at base, preserved up to 6 m height, standing on top of the ...

Seismic Safety Analysis of Interlaminar Rock Mass in the Distributed Underground Reservoir of a Coal Mine

Water
This study focuses on the seismic safety of distributed underground reservoirs in coal mines, especially in scenarios involving the establishment of multiple reservoirs within the same mining area, spanning different coal seams. Dynamic similarity model tests and numerical simulations are employed to investigate the construction and operation of these ...

Excavating the iconic: The rediscovery of the Fairbottom Bobs Colliery pumping engine [PDF]

, 2004
Steam engines were one of the first machine-types to attract the attention of antiquarians and later Industrial Archaeologists. From the first Newcomen engine in 1712 to the 20th-century steam turbine, these objects still exert a fascination for ...
