Gas gushing and the co-mining of coal and gas outbursts are common disasters in coal mines. The weakening of thick–hard main roof fracturing can effectively alleviate the gas overrun in the initial mining stage. Four numerical simulation schemes we

The coupling failure induced by the influence of mining practice and the water immersion softening of the water-resisting coal pillars in old goaf is one of the common causes of water inrush accidents in the same seam working face. Exploring the fail

Fracturing hard roofs by ground hydraulic action is an important control technology for the strong mine pressure in the stope. In this paper, a new simulation method, “separate + interface,” is proposed, and two physical simulation experiments ar
