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 RFPA
2D-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".
