| 摘 要： | 为了有效治理新安煤矿16020回采工作面顶板突水,探讨了顶板突水在邻矿老空水补给情况下的治理技术。结果表明:首先通过水位、水质、水温等因素对其突水水源和导水通道进行准确快速判别,再利用帷幕注浆堵水切断顶板水补给通道在本次顶板突水治理中具有明显效果,历时三个月成功封堵补给通道,堵水取得成功。对于有老空水补给的顶板突水,帷幕注浆切断补给通道是一种行之有效的治水方法,该技术方法对具有相似类型顶板突水的矿井具有一定的借鉴意义。

| Abstract: | In order to effectively control the roof water inrush of 16020 working face in Xin'an Coal Mine, the paper discusses the technical problems of the roof water inrush under the condition of the old empty water supply by using the knowledge of hydrogeology, coal geology, mining, grouting and so on. The results show that: first of all, through analysis of the water level, water quality, water temperature and other factors to accurately and quickly identify the water inrush source and water diversion channel, and then use curtain grouting to cut off the roof water supply channel in this roof water inrush treatment is effective. It took three months to successfully block the supply channel, and the water blocking was successful. For the roof water inrush with old air water supply, curtain grouting is an effective way to cut off the supply channel, the technology can be used for reference for similar roof water inrush. |
