摘要：T he function s of b lasting in coal seam are analysed acco rding to the p rincip le of the spherical2shell2destab ilization theo ry. It is app roved that the blasting of dynamite does not increase the outburst danger of coal seam; bu t, w hen the coal seam is associated by some hard and so lid bo ttom o r roof, the roof fall of coal body in cru sh ing zone would be caused by blasting. This could explain the reason of the outburst phenomena, which take place when a tunnel passes one cross gate and a hard rock stratum is blasted.
