摘　　要：在概述五图-双系数法基本原理的基础上,对山东泰安煤矿最下部带压开采的13号煤层进行了突水危险性评价。评价以"带压系数"为主要评价指标,结合"突水系数",并配合"三级判别",进行带压等级分区,评价结果显示:13号煤层带压开采区底板突水危险性主要划分为Ⅰ、Ⅱ、Ⅲ级区,其中以Ⅱ、Ⅲ级区范围较大,Ⅰ级区仅分布在断层周围。说明13号煤层带压开采区底板突水危险性较小,安全性较高,但在带压区开采13号煤层时应加强断层或隐伏构造探查与防治。Based on summarization of the＂five figures plus double coefficients method＂fundamental, carried out water bursting hazard assessment for the mining of coal No.13 under safe water pressure of aquifer in the Taian coalmine, Shandong. Taking the＂pressure coefficient＂as main assessing index combined with＂water bursting coefficient＂and coordination of＂three leveled discrimination＂carried out pressure grade zoning. The result has shown that the floor water bursting hazard in coal No.13 mining area can be partitioned into category I, II and III areas, in which the extent of II and III categories is rather large, while category I only distributed near faults.This shows that the mining of coal No.13 under safe water pressure of aquifer has little floor water bursting hazard with higher security,but fault and buried structure prospecting and control should be strengthened in pressurized mining area.
