| 中文摘要 | 针对影响安全生产的问题———突冒危险性,结合唐山石人沟铁矿的具体地质条件、采矿体条件、岩体的结构特征及力学性质测试,借助MSC.PATRAN和MSC.NASTRAN三维数值模拟软件进行建模分析,确定出岩体力学参数,从而对矿床进行稳定性分析,最后总结得出合理的境界顶柱厚度,提出确保顶柱稳定的采矿方案、措施、建议以及有效的防止矿体突冒控制技术措施。为其他矿山露天转井下开采顺利进行提供科学依据。; In view of the danger of spontaneous caving, a problem in safety production, modelling analysis was made to determine the rock mechanical parameters by means of MSC.PATRAN and MSC.NASTRAN 3D numerial simulation softwares on the basis of the site-specific geological conditions, orebody conditions, structural features of the rockmass and testing of its mechanical properties in Tangshan Shirengou Iron Mine.The stability of the deposit was then analyzed and the reasonable thickness of boundary crown pillar was finally obtained.The mining scheme, measures and suggestions ensuring the stability of crown pillar and the effective technical measures for preventing the spontaneous caving of orebody were proposed, providing a scientific evidence for a smooth transition from open-pit to underground mining.; 国家自然科学基金重大项目(50490270); 国家自然科学基金项目(50204003,50174013)。 |
