摘　　要：四川省煤矿区水文地质条件复杂,岩溶水对煤矿安全开采构成较大的威胁。在分析四川省含煤地层特征的基础上,系统研究了四川省煤矿区岩溶水分布特征和赋存形态,并通过分析经典案例得出岩溶突水的原因主要为自然原因和人为原因,提出了通过加强煤矿水文地质补勘、疏水降压开采、优化排水系统、选择合适采煤工艺、落实企业防治水主体责任等岩溶水综合防治措施。The hydrogeology condition of Sichuan coal mine area is complex;karst water is a big threat to safety production of coal mines.On the basis of analyzing coal-bearing strata characteristics,the distribution characteristics and occurrence forms of karst water in Sichuan coal mine area are systematically researched,by analyzing the classic case,the reasons of karst water burst mainly include nature reason and human reason,and the comprehensive measures of karst water treatment with hydrogeology supplement exploration,dewatering mining,optimizing the drainage system,choosing the best mining method,implement enterprise ＇s main body responsibility are proposed.
