矿井防治水安全技术探讨

Safety Measures Against Water Hazard of A Coal Mine

对垞城煤矿开采过程中防治水安全技术经验进行总结,通过对矿井不同区域的水文地质情况分布特点进行分析、研究、找出规律,采取上行式开采、疏水降压、疏放老空水、改变工作面布置方式等方法,从采煤面设计、安装到生产多环节采取针对性的预防措施,有效地解决了水害威胁,为生产的正常进行创造了良好条件,保证了安全生产,为同类条件下矿井防治水提供了宝贵经验。

The author introduced in this paper the practice against water hazard during the production in the Chacheng coal mine.Based on the analysis and research of the specific distribution of hydrographic geology in the different area in this mine,the rule is discovered.And some measures are adopted,such as up direction mining,lowering water pressure by water draining off,escaping waste ares water and changing the manner of laying out a face etc.Thus all there are measures in the techs from designing to setting or operating.These solve efficiently the water hazard and create a good condition for safe conduction.Tialso provided the other coal mines the valuable experiences.
