| Abstract: | The strip mining simulation of greatinclined and multiple coal seams with 3dimensions finite element method is researched. The interrelation is analysed among ground subsidence, coal pillar stress and mine coal seam amount, seam spacing, sizes of strip mining, strip relative positions, recovery ratio, strip mining along the seam strike. A definite method of strip mining sizes is made for the strip mining of greatinclined and multiple coal seams. The theoretical foundations are provided for the engineering practices. |
