摘　　要："下三带"理论经过多年的理论研究和生产实践已发展的日益完善,该理论在承压水上安全开采评价及矿井底板危险性评价中起了重要作用。本文对"下三带"理论的概念作了较系统的论述,并着重以笔者参与的实例,结合压水试验和有效隔水层突水系数法,来对其在煤层底板突水危险性评价的应用加以说明。本文旨在促进对该理论的深入理解,更好的推广应用,为矿井安全生产服务。Recent years of researches and production practice have made the＂ Down Three Zone＂ theory more and more perfect. The theory plats an important role in the risk evaluation of the coalbed floor. This paper summarized the development and application of the＂ Down Three Zone＂ in nearly recent several years, which systematically exposed the concept. At last, combining pressure test and water inrush coefficient method ,writer give an example which apply＂ Down Three Zone＂ in the risk evaluation of the coal- bed floor. This paper aimed to the intensive comprehension to the theory and the extensive application of the methods in the coal mining production.
