发布时间:2019-02-16 02:27
【摘要】:为解决复杂地质条件下煤层瓦斯压力测定过程中存在的问题,提高封孔质量,提出了双囊袋带压注浆封孔技术,并在郑州市磴槽集团磴槽煤矿进行了试验。双囊袋带压注浆封孔技术采用高压注浆能有效地封堵钻孔裂隙,减少封孔工序,提高了可操作性和使用安全性。
[Abstract]:In order to solve the problems existing in the determination of gas pressure in coal seam under complicated geological conditions and improve the quality of sealing holes, the paper puts forward the technique of sealing holes with pressure grouting in double sacks and carries out tests in Dengguo Coal Mine of Dengguo Group, Zhengzhou City. High pressure grouting can effectively seal the hole cracks, reduce the sealing process, and improve the operability and safety.
