Affection Laws of Atmospheric Pressure to Gas Emission at Fully Mechanized Working Face

open access: diamondProcedia Engineering, 2014
AbstractGas emission is affected by many factors. Effects of atmospheric pressure on coal mine gas emission have become a rising concern. Basing on the gas emission at Y485 fully mechanized working face of Tangshan mine and atmospheric pressure, the paper had carried out online monitoring with sensors for 20 days continuously.

Roof stability analysis model of super-long fully mechanized working face and its application [PDF]

open access: goldGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Abstract The strata behavior of a fully mechanized working face is obviously different from that of a short working face after the dip length of the coal face is lengthened. In view of the characteristics of high frequency, high peak value and large range of weighting in super-long working faces, a mechanical analysis model based on elastic foundation ...
