摘要
根据凤凰山矿151309工作面现场数据,运用Fluent软件模拟了该工作面采空区在不同通风量情况下三带的分布情况;根据采空区自燃"三带"理论及其划分主指标,结合该工作面现场"三带"的观测数据,在配风量为1 300 m3/min时,分析了采空区O2浓度的变化规律,确定了采空区三带的分布情况,与模拟结果基本一致,验证了模拟结果的正确性,为后期采空区自燃的防治提供了依据。
According to the field data from 151309 working face of Fenghuangshan coal mine,simulates the three zones distribution regularity of the working face goaf in different ventilation quantity situation by using Fluent software.According to the theory of spontaneous combustion three zones in goaf and the divisiory main indicators,combines with three zones observational data of in the field.Analyzes the change rules of O2 concentration in goaf,confirms the distribution of goaf three zones when the air volume is 1 300 m3/min,it is consistent with the simulation results,it verifies the correctness of the simulation results,and can provide a basis for prevention and treatment the goaf spontaneous combustion.
