Study on evolution law of overburden fracture in fully-mechanized top-coal caving face with large mining height in thick coal seam

Fully mechanized top-coal caving mining with large mining height is easy to form strong strata behavior, and the fracture evolution law of overlying strata is very important for safe production of working face. Taking the 160206 working face of Yangchangwan Coal Mine as the engineering background, t...
