摘要
探讨了破碎带下矿体开采引起地表沉陷的地质现象和产生机理,并介绍了离散元法的原理和常用离散元软件UDEC的特点及其控制参数的选择方法,利用该软件结合某铜矿山的具体工程地质情况,对破碎带下采矿产生地表沉陷的地质力学现象进行了数值模拟,验证了该机理的正确性。
Mechanism and phenomenon of subsidencc induced by mining under fragmentized rock - strip was analyzed in the paper. Discrete element method, DEC and control parameters of the UDEC were introduced. The mechanism was testified with discrete element numerical simulation through an engineering example.
