An effect evaluation method of coal seam hydraulic flushing by EMR

Journal of Natural Gas Science and Engineering, 2018
Abstract Present coal seams in China are characterized by great gas pressure and content, low permeability features, and thus, the extraction of gas is difficult and gas disaster remains serious. To improve the permeability of coal seam, the hydraulic flushing is adopted, so the effect evaluation of stree relief and permeability enhancement will be ...

Hydraulic Settling of Flushed Swine Manure A Case Study

Applied Engineering in Agriculture, 1987
ADAPTION of flushed manure management systems for modern swine production facilities has reduced labor managment problems, but in doing so has created new problems. Typical problems may include odors from lagoons or other liquid storage structures, and the managment of labor and equipment involved with recycling flush water or field applications ...

HYDRAULIC MODELLING OF TIDAL CIRCULATION AND FLUSHING IN COASTAL BASINS.

Proceedings of the Institution of Civil Engineers, 1989
The paper highlights the increasing concern of planners and designers for the hydroenvironmental problems relating to tidal circulation and flushing in small coastal basins, harbours and marinas, and the use of physical and mathematical models as design tools to address such problems.

Numerical Simulation on Effective Influence Radius of Hydraulic Flushing Borehole

Advanced Materials Research, 2012
In this paper, according to the mechanics balance equation, the law of conservation of mass and the relationship between parameters including coal seam permeability, porosity and volume strain, we build a gas-solid coupling model of hydraulic flushing borehole in the coal roadway floor, and use the model to investigate the relationship between ejected ...
