Abstract
A kind of rock cross-cut uncovering technology was put forward.The problems of long cycle and poor safety in the process of rock cross-cut coal uncovering were solved by sealing a section of uncovering coal roadway and injecting certain pressure of air.Several key issues of this technology were analyzed and illustrated by laboratory experiment and field investigation.The result showed that the technology can achieve better security result and realized the purpose of preventing effectively.
