东山煤矿五和七采区15号煤层底板突水脆弱性评价

摘要

通过分析五、七采区矿井地质及水文地质条件，采用“脆弱性指数法”对五、七采区15号煤层底板突水进行了评价，将五、七采区划分为底板突水脆弱区、较脆弱区、过渡区、较安全区、相对安全区，可以据此在生产中针对具体情况采取相应防范和治理措施，从而确保安全生产。%Through the analysis on geological and hydrogeology conditions of 5,7 mining area mine,this oaoer using“vulnerability index meth-od”to evaluate the floor water inrush of 5,7 mining area No. 15 coal seam,made the 5,7 mining area divided into floor water inrush vulnerable area,relatively vulnerable area,transition area,relatively safe area,related safe area,could based on this took corresoonding orevention and control measures in oroduction according to soecific circumstances,so as to ensure oroduction safety.
