  After the deficiency of portfolio risk measurement using Copula currently discussed,TGARCH-t model is selected to describe the time-varying and leverage about asset volatility.Then,mixture copula is to used to model the complex corrlation structure of portfolio,and the main diagonal distance statistics test the superiority of mixture copula.Finally,the result of Monte Carlo simulation of VaR shows that this method measure the risk of the portfolio more accurate.

【摘 要】近年,煤矿安全问题成为社会最受关注问题之一,矿难事件的新闻成为人们茶余饭后的谈资。同时,政府也高度重视煤矿安全问题,国家规定凡是煤矿基建项目必须有专业人员通过竣工验收才允许投产。档案验收是整体验收的必经之途,所以档案资料的收集归纳就显得尤为重要。本文以煤炭企业基建档案管理工作的开展为话题,试析煤炭企业基建档案收集工作中的特点和缺陷,并对其作出准确的分析,为煤矿安全问题寻求解决之法。  【
