摘要：选择高、中、低三档家具博览城进行调研,借鉴现场监测出入口行人流、分时统计流量的方法设计典型家居博览类市场待疏散人员数目的确定方法,分析人员密度调研结果,将其应用于某大型家具商场人员疏散安全性评估中。结果表明:确定的人员疏散密度符合家具商场实际,可用于大型家具商场的人员疏散安全性评估。在火灾自动灭火设施有效的情况下,设计的疏散宽度能够满足人员疏散要求。

摘要：针对某大型地下金属矿山存有大量复杂边界矿柱的工程实际,为了优化设计复杂边界矿柱回采崩矿方式,结合CMS精密探测技术,运用矿山三维建模软件SURPAC对复杂边界矿柱进行了三维可视化建模.在此基础上,构建了复杂边界矿柱的块体模型,并导出其数据文件,采用接口程序将其导入数值分析软件FLAC3D中,实现了复杂边界矿柱数值模型的快速准确构建.模拟分析了后退式侧向崩矿和水平上向分层崩矿2种可行的回采崩矿方式,结合模拟过程中矿柱及充填体的力学响应特征,实现了复杂边界矿柱回采崩矿方式的数值优化.

摘要：In order to ensure overall optimization of the underground metal mine production scale, multidisciplinary design optimization model of production scale which covers the subsystem objective function of income of production, safety and environmental impact in the underground metal mine was established by using multidisciplinary design optimization method. The coupling effects from various disciplines were fully considered, and adaptive mutative scale chaos immunization optimization algorithm was adopted to solve multidisciplinary design optimization model of underground metal mine production scale. Practical results show that multidisciplinary design optimization on production scale of an underground lead and zinc mine reflect the actual operating conditions more realistically, the production scale is about 1.25 Mt/a (Lead and zinc metal content of 160 000 t/a), the economic life is approximately 14 a, corresponding coefficient of production profits can be increased to 15.13%, safety factor can be increased to 5.4% and environmental impact coefficient can be reduced by 9.52%.
