摘要
针对松藻矿区地质采矿条件,从弹性力学和随机介质理论出发,导出了采动地表溶洞顶板拉裂及稳定性计算模型;建立了溶洞跨距、埋藏深度及开采移动变形之间的数学关系;分析了在松藻矿区基岩裸露条件下,浅地表溶洞受采动影响的变形破坏规律。
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.
