Overburden destruction structure model and mechanism of mine pressure in Caojiatan coal mine with 10 m super large mining height

Meitan xuebao
The successful mining of 10 m ultra-high working face in Caojiatan coal mine marks a new level of full height mining technology in China’s extra-thick coal seam. Based on the pressure, displacement and energy sensors, the mining of ultra-high mining face is monitored comprehensively, the characteristics of mine pressure behavior were clarified, the law
