为解决厚煤层一次采全高综采工作面上隅角瓦斯积聚难题,采用工艺巷通风法和高位抽放钻孔技术相结合的方法,通过数值模拟对这项技术进行了验证,并在汾西曙光矿1210工作面进行了现场应用,取得了良好效果,为厚煤层一次采全高综采工作面上隅角瓦斯的防治工作提供了新方法。
In order to solve the problem of methane accumulation in the upper corner of fully mechanized fully mechanized top coal caving mining face once in thick seam, this technique was verified by numerical simulation using the method of combining technology ventilation with high draft and drainage holes, 1210 working face of Shuguang Mine has been applied on site and good results have been obtained, providing a new method for the prevention and control of methane in the upper corner of the fully mechanized top coal caving mining face once in the thick seam.
