摘要
封闭不良钻孔导水突水事件是煤矿安全生产的一大隐患。对神东布尔台煤矿巷道揭露封闭不良钻孔及突水钻孔出水层位进行了研究。查明出水层位及其下部承压水富水性后,利用钻探对承压水进行了疏水降压,并利用钻探孔注浆对底板隔水层进行了改造,制定完善了工作面过封闭不良钻孔安全技术措施。通过从源头治理隐患,到制定专项措施防治隐患等手段,最终工作面顺利通过封闭不良钻孔突水区域。
The water inrush event of poor sealing borehole is a hidden danger in coal mine safety, and this paper presents a study on the tunnel in Buertai Coal Mine disclosing poor sealing drilling and inrush layer of water inrush boreholes. Identifying the water inrush layer and the water yield property of its lower confined water, in this paper, the drainage and pressure relief of the confined water was carried out by drillings, and the drilling hole grouting was used to transform the water-resisting layer of floor, and the safety technical measures for the safety of the poor sealing drillings in the working face have been developed. Through controlling hidden trouble from the source, the development of special measures to prevent and control the hidden danger, the working face smoothly passed through the poor sealing drilling area finally.
