C. STEMMING: Stemming materials provide confinement and prevent the escape of high pressure gases from blasting holes. This material must be free from rocks and properly tamped. Inadequate stemming results in stemming ejection from the holes resulting in flyrocks. In general, the stemming length should not be less than 25 times the blast hole diameter(Sheridan, 2002). Konya and Walter (1990) recommended length of stemming to be 0.7 times the burdenC.镗削：停止材料提供约束并防止高压气体从爆破孔中逸出。 这种材料必须没有岩石和适当夯实。 不足的梗阻导致从孔中排出的梗阻导致飞石。 一般来说，梗塞长度不应小于爆破孔直径的25倍（Sheridan，2002）。 Konya和Walter（1990）建议茎梗长度为负荷的0.7倍
