Instability-negative pressure loss model of gas drainage borehole and prevention technique: A case study.
The internal collapse of deep seam drainage borehole and negative pressure loss represents a serious technical problem affecting gas drainage. To address this problem a creep model of coal around borehole was established based on the plastic softening characteristics of coal. The final collapse time...
