Forecast Model of Spontaneous Combustion in Goaf of Close Distance Coal Seams

摘要

This paper analyzes characteristics and correlation hypothesis of goaf of close distance coal seams, and makes correlation hypothesis of goaf of close distance coal seams, and makes use of spot observation relevant data in working face of close distance coal seams of the DongRong 2nd coal mine, and sets up forecast model of spontaneous combustion in goaf of close distance coal seams. It uses GAMBIT for setting up regional model of numerical simulation and dividing mesh, and defines parameters of close distance coal seams by UDF, and makes use of the FLUENT6.0 of CFD software for resolution. This indicates the forecast model can be used to forecast the danger zone of spontaneous combustion and can obtain good result that tally with the reality.
