The forth part presents the experiments on fire area resistance and retroversion of fire smoke by using integrative fire simulation system of mine laneway network, with the results compared with the simulative numerical value, and the part also brings forward a new conception named fire area resistance which reflects character of fire resistance of mine laneway network. A general dimensionless calculation formula is deduced which presents the rule of smoke retroversion distance when fire occurs.
