摘要
结合某金矿二步回采,胶结充填工艺,采用有限差分数值软件FLAC3D模拟非线性大变形问题,建立数值模型,模拟矿体的回采和充填过程,为安全开采提供了依据,论证了胶结充填的可行性,保证安全生产。
Combined with a gold mine in which cemented fill process in two steps is applied, analysis is conducted of the stress and displacement of surrounding rock and filling mass in the sto ping process by a model built with FLAC^3D, enabling safe stoping of ore block , clarifying viability of cemented fill and ensuring safety in production.
