“两堵一注”封孔技术在松软煤层中使用的试验研究

Experimental Study on the Application of Two-plug-in-hole Technology in Soft Coal Seam

本文运用平顶山安泰华公司的FKQW-50/0.6"两堵一注"封孔器封孔工艺,在河南能源云盖山煤矿进行了试验研究,认为"两堵一注"封孔器封孔工艺注浆压力大,能主动支护钻孔,进一步减少漏气通道,抽采效果更好。

In this paper,the FKQW-50/0.6"two-shot-one-shot"sealing process of Pingdingshan Antehua Company was used to study the energy of Yungushan Coal Mine in Henan Province,and it was considered that the"two-Grouting pressure,can take the initiative to support drilling,to further reduce the leakage channel,extraction effectto further improve.
