Numercal Simulation and Application Research on Enrichment Law of Pressure Relief Gas in Adjacent Seams

摘要：

In order to solve gas concentration exceeding limit caused by the phenomenon that mining - affected pressure relief gas in adjacent seams emit into stope, the migration and enrichment law of pressure relief gas in the mining — affected fracture field was simulated by using CFD technology.The drainage schemes for pressure relief gas in adjacent seams was developed based on simulation results, and the validity of the drainage scheme was verified through on — site investigation.The results show that the adjacent drainage scheme effectively eliminate the phenomenon of gas concentration exceeding limit at the mining face.CFD simulation of the pressure relief gas enrichment can provide the basis for adjacent seams drainage plan.
