摘　　要：通过对煤体进行变频激振试验,研究了振动频率的变化对煤体裂隙发育的影晌.根据煤体受振后煤体裂隙的分布和力学性能的比较,我出了受振煤体裂隙发育规律和媒体裂隙发育的频率特征.为用振动方法致生煤体裂隙防治冲击地压的理论提供了实验依据.The paper studied the coalmass crevasse growing rule acting of different frequency vibrating. Through the coalmass crevasse growing and comparison of the mechanical property arfter vibrating,the frequency character of the coalmass crevasse growing was discovered.
