Effects of Different Factors on the Mining of Extra-Thick Coal Seam
2018Based on the mining case of Dafosi Coal Mine in Shaanxi Province, which is a typical coal mine with extra-thick coal seam, the effects of mining width, buried depth and rock grade on the ground surface deformation and sur-rounding rock stress have been studied by numerical experiments.

Research on the overburden deformation and migration law in deep and extra-thick coal seam mining
Journal of Applied Geophysics, 2021Abstract To understand the problem of water damage to the roof caused by instability and deformation of overburden deep coal seams in the Ordos mining area, the rock stratum migration mechanism was analyzed according to the geological conditions of the Tangjiahui coal mine, and a vertical borehole observation system was established based on the ...
