Study on the Influence of the Location of Dirt Band on Top Coal Caving Property in Extra-Thick Coal Seam

Geotechnical and Geological Engineering, 2020
The influence of dirt band on the top coal caving property is usually analyzed from the thickness and hardness of the dirt band. For the extra-thick coal seam with a thickness of more than 20 m, the location of the dirt band also has a huge impact on the top coal caving property. In this paper, No.
