Innovative Approach for Heating of Buildings Using Water from a Flooded Coal Mine Through an Open Loop Based Single Shaft GSHP System

, 2015
Geothermal energy, deep and shallow, has always been identified as an important renewable energy resource. The stable temperature and relatively low enthalpy of mine water contained in the abandoned and flooded coal mines have the potential to form a ...

The design and development of an innovative simulator for an open loop system for extracting energy from flooded coal mines

, 2015
Water source heat pumps, in comparison to air-to-air heat pumps, have significant advantage for heating or cooling applications due to the relatively regulated temperature of most water resources.

Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Study on the failure and acoustic emission characteristics of coal under graded cyclic loading and unloading stress paths

Scientific Reports
To study the influence of cyclic disturbance stress on the mechanical behavior of coal during mining, a gas containing coal fluid-solid coupling servo seepage experimental system was used to conduct experimental research on the acoustic emission (AE ...

Reclamation of the Enugu Coal Mine Site at Abandonment

Indian Journal of Environment Engineering, 2021
Mining of coal (fossil fuel) resources in Enugu resulted in groundwater pollution/depletion and left the mine site with the potentials of air pollution, loss of landscape/aesthetic degradation and soil contamination. Other Environmental impacts were extensive soil damage, alteration in microbial communities and affecting vegetation leading to ...
