摘要
通过对煤的振动实验,研究了煤受振前后裂隙发生、发展规律以及弹性模量、降模量和抗压强度的变化规律,为煤体振动方法用于现场提供了物理基础。
Abstract Through vibration experiment on coal samples,changes in fissure/fracture structure,elastic modulus,and compressive strength of coal after being shaken have been investigated and compared to properties of the coal sample before being shaken,so as to provide a physical basis for in situ use of so called coal seam vibraton method.
