摘　　要：白皎煤矿近距离煤层群赋存条件下区域漏风复杂,工作面层间漏风严重,对防火工作极为不利。以2274工作面区域为例,开展SF_6示踪气体漏风测试技术工艺研究,查找漏风通道并掌握漏风规律,为分析2274工作面上覆老空区隐患范围,针对性采取预防措施提供技术支持,保障了该工作面安全回采。Under the condition of the close distance coal seam group in Baijiao Coal Mine, the air leakage is complicated and the air leakage is serious to the working face. Taking the area of 2274 working face as an example, this paper carried out the research of SF6 tracer gas leakage testing technology, finds out the air leakage channel and grasps the law of leakage, and provides technical support for analyzing the hidden danger range of the old empty area in 2274 working face and takes preventive measures, and guarantees the safe mining of the working face.
