矿井外因火灾局部反风FDS数值模拟

FDS Numerical Simulation for Partial Inverted Ventilation of Exogenous Mine Fire

摘要: 采用FDS数值模拟的方法，建立了某矿的几何模型，对火源在进风巷以及火源在工作面时反风的情况进行模拟，研究了2种工况下各巷道的温度场分布情况、烟气流动情况、可见度情况等。研究结果表明，当火源在工作面进风巷道时，及时采取反风措施，能有效的将烟气控制在上流，有利于人员的疏散，防止灾害扩大。

Abstract: The geometry model was set up by using FDS which simulated the inverted ventilation situation when the fire source was in the working face or intake airway, the paper studied the temperature field, smoke spread, and the visibility. The simulation results showed that it's necessary to adopt the anti-wind measures in time when the fire source was in the intake airway, it can effectively control the smoke to spread to the downwind, and is benefit to the evacuation, and prevents ravage expansion.
