摘要
唐口煤矿6305综放工作面瓦斯涌出量较高,采空区自燃危险性较大。针对工作面自然发火和瓦斯涌出问题,提出工作面架间间隔灌注隔离采空区技术,人为的构建间隔一定距离的非连续隔离墙体,改变采空区后方风流场的流动。实验结果表明,架间间隔灌注隔离采空区技术能够有效地降低工作面瓦斯及CO浓度,保障了工作面的安全回采。
The gas emission rate of Tangkou coal mine 6305 fully mechanized caving mining face was high, and the risk of spontaneous combustion in goaf was large. On this issue, the Fire Prevention Dynamic isolation Technology of Goaf was proposed and spaced apart discontinuous walls were artificially established. The flow field of the wind field behind the goaf was changed, and the experiment was carried out in the field. The results show that: the fire prevention dynamic isolation technology of goaf can effectively reduce the face gas and CO concentration, to ensure the safety of mining face.
