    Cooperative and Fast Outburst Prevention Technology of "Deep Injection and Shallow Gas Drainage" for Coal Roadway

    • 摘要: 基于水驱替瓦斯理论,提出了“深注浅抽”交变协同快速消突技术。通过RFPA2D-Flow模拟软件对“深注浅抽”快速消突技术进行了数值模拟,对单孔定向,双孔定向进行了注水压裂模拟试验。试验表明:在定向孔存在的条件下,注水压裂效果更加显著,卸压增透更加彻底。同时,对“深注浅抽”快速消突技术的钻孔布置方式进行了研究,提出了循环递进式“深注浅抽”快速消突技术的钻孔布置方式。

       

      Abstract: Based on the theory of driving and displacing gas by water, then proposed the cooperative and fast outburst control technology of "deep injection and shallow gas drainage". Through the software of RFPA2D-Flow, it made numerical simulation for this technology, and it carried out simulation test for single-hole orientation and double-hole orientation. The results showed that the effect of water injection fracturing was more significant, relief and antireflection effect was more thorough under the existence of oriented hole. At the same time, it studied borehole arrangement patterns of the fast outburst control technology of "deep injection and shallow gas drainage", put forward the borehole arrangement pattern of fast outburst control technology of cyclic and progressive "deep injection and shallow gas drainage".
