Numerical Simulation Analysis about the Initial Pressure of the Stope under Gob in the Close Distance Coal Seams
On the large mining height and fully-mechanized subject of the second mine of Pingshuo,the authors have drilled holes for coring and tested the properties of coal rock,use the FLAC2D to simulate and analysis the values and the first characters of the first mining face of large mining height and fully-mechanized mining in close distance coal seams,and finally determine the display mode roof surrounding rocks instability and judge the roof weighing step and intensity.
