A new technology for coal and gas control based on the in situ stress distribution and the roadway layout

An auxiliary gas control technology is described that can reduce coal and gas outburst accidents when there is no existing protective coal seam and gas pre-draining is not effective. Numerical simulation methods were used to study the stress distribution ahead of the roadway face for different in si...
