摘　　要：采用3Dmine软件,对开采错动范围内矿岩进行多个采剥境界方案建模、分析与研究;采用4种定量(半定量)方法计算并结合FLAC^(3D)软件验证露天采剥与地下采矿隔离矿柱的稳定性;采用Slide6.0软件分析其采剥境界最终边坡的稳定性。经研究,最终确定648m采剥境界方案合理可行,露天采剥与地下采矿同时进行的隔离矿柱安全厚度为50m,最终边坡角45°。Modeling, analysis and research of multiple schemes for stripping ratio of pit limit for ore bearing rock in the fault dy-namic range were made by using 3Dmine software. The stability of isolated pillars in strip and underground mining operation was cal- culated and verified by four quantitative （semi quantitative） meth- od in combination with FLAC3D software. The stability of the final slope of the stripping ratio of pit limit was analyzed by using Slide6.0 software. By study, it was ultimately determined that the scheme for 648m stripping ratio of pit limit is reasonable and feasi- ble. The safety thickness of isolated pillar at 50m in the simultane- ous operation of open-pit and underground mining is safe and relia- ble and the final slope at an angle of about 45 degrees is stable and reliable.
