STUDY ON THE WORKING FACE FLOOR DAMAGE AND GAS EMISSION
In order to understand the gas emission from lower adjacent seam on this layer, the effect of working face mining on floor is discussed, and the stress condition of floor is also analyzed. It is summarized that the cause for the gas emission is the parameter of floor fracture, through which the gas rushes into exploitation bed from lower adjacent seam. The discussion on gas emission of lower adjacent scam provides theoretical direction for arrangement design of low position drilling at floor. At last, this theory has been applied in practice, and a good effect is realized.
