Study on Spontaneous Combustion “Three Zones” of the Distribution Law and Integrated Fire Prevention Technology in Mined-Out Area of Lingquan Mine

Table 3

The distribution law of “three zones” combined with measurement and simulation in the goaf.

Position	Heat dissipation zone/m	Oxidation zone/m	Suffocation zone/m	Maximum width of oxidation zone/m
Return air side	＜25	25–62	＞62	37
Middle	＜40	40–96	＞96	56
Air inlet side	＜46	46–75	＞75	29
