摘要
运用Fluent软件模拟掘进巷道抽出式通风粉尘浓度变化规律;并现场实测某铁矿东区2655m水平12#进路掘进工作面的粉尘浓度,对比分析实测与模拟结果表明:模拟计算结果与现场实测数据变化趋势基本一致,在模拟时间达到1000s时掘进巷道粉尘浓度就已达到安全标准。
The dust concentration change rule in the exhaust ventilation of excavation roadways was simulated using software FLUNET and the field measurement was made of dust concentration in 12# heading face at level of 2655 m in the eastern area of an iron mine. The results indicate that the simulation results are consistent with the change trend of the measured data and the dust concentration of in excavation roadways with 1000 s. has reached a level in safety standards.
