摘　　要：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。To solve the problem of gas accumulation in the upper comer of all high fully mechanized working face in the thick coal seam, it adopted the comprehensive method of technique roadway ventilation and high drainage drilling technology. This technology was verified through numerical simulation and the field application of working face 1210 in Fenxi Shuguang Coal Mine, it had achieved good results, which provided a new method for gas prevention and control in the upper comer of all high fully mechanized working face in the thick coal seam.
