摘要
针对山西某矿采空区瓦斯治理,确保工作面隅角、回风流瓦斯浓度不超限,对I010203综放工作面实行高位钻孔和上隅角采空区插管抽放作为抽采瓦斯试验方案。通过对现场施工和实测数据对比分析,应用上隅角采空区插管抽放技术的抽采效果十分明显,工程施工费用较低,该抽采技术适用于该矿井采空区瓦斯治理。
In view of the gas control in the goaf of a mine in Shanxi,in order to ensure that the gas concentration in the corner and return air flow of the working face does not exceed the limit,the high-level borehole and intubation drainage in the goaf at the upper corner of I010203 fully mechanized caving face are implemented as the test scheme of gas drainage.The comparative analysis of field construction and measured data shows that the drainage effect of the upper corner goaf intubation drainage technology is very obvious and the construction cost is low.The drainage technology is suitable for gas control in the goaf of the mine.
