Numerical modelling of the goaf : methodology and application
2016The mechanical behavior of the goaf is a critical issue that may affect the efficiency of longwall mining. Goaf numerical modelling as a continuous material is a challenge, especially because its large-scale mechanical properties are not precisely known.

Goaf drainage at Moranbah North Coal
The Australian underground coal industry is demanding greater production rates from gassier coal seams. This demand has increased tailgate gas concentrations within mines due an increase in specific emissions. Post drainage of a longwall goaf is required when current gas management plans are unable to manage increased gas specific emissions from the ...openaire +2 more sources
