- •
We study mechanisms of goaf gas drainage with horizontal boreholes.
- •
Properly placed horizontal boreholes create low pressure sinks to change gas flows.
- •
Horizontal boreholes can be an efficient means of goaf gas drainage.
- •
We proposed a concept of horizontal gas drainage through goaf pressure control.
