To prevent the caved area of a colliery from spontaneous fire and to find it as early as possible,an equation is given with analytic solution and proved in conformity with the actual situation,of which the pattern of gas moving in the area is expressed.

Temperature in compartment fires is one of important parameters in fire science with great importance for fire protection.

In this paper,radiative heat transfer method is applied to study the distribution of net heat flux of a combustible surface on a horizontal plane and a vertical line in a compartment fire.

It achieves three-dimension field simulation of compartment fire process.

State of the art report of research on the stage of flashover in compartment fires;

Causes of mine fire hazard are analyzed and intelligent fire fighting valve is presented, which is made of memory alloy and self-extinguishing can b e carried out.
