摘　　要：为了研究新义煤矿煤层底板的突水危险性,分析了矿区的水文地质条件,设计了底板采动破坏的测试方案,结合FLAC数值模拟软件和经验公式对底板采动破坏深度进行了分析,采用考虑矿压影响的斯列萨列夫公式对底板突水危险性进行了评价,为新义煤矿的安全合理开采提供了科学依据。In order to study coal floor water bursting hazard in the Xinyi coalmine,mine area hydrogeological condition was analyzed,and floor mining destruction testing scheme designed.Combined with FLAC numerical simulation software and empirical formulae carried out floor mining destruction depth analysis.Using Slisalif formula considering strata pressure impacts carried out floor water bursting hazard assessment,and provided scientific basis to Xinyi coalmine safe and rational mining.
