| Abstract: | Based on the specific geological and mining condition in Songzao mining area, a mathematical model of pull cracks and Stability on the top plate of solutoan cavity in moving earth's surface for mining is derived through the theories of elastic dynamics and random medium.The mathematical ralation among the span of solution cavity, burial deepnees and moving deformation for mining is also set up. Under the condition of exposed basement rock in Songzao mining area, the deformation law of destruction of solution cavity in sballow-terrain is analysed. |
