中文摘要：
声发射技术和CT扫描技术是监测煤岩体裂纹扩展的重要手段。概述了声发射及CT扫描实验在煤岩体领域的发展历程和应用现状。结合声发射技术与CT扫描实验的优点，提出声发射与CT相结合进行煤岩体实验的研究方向，以便于有效结合煤岩体内部裂纹变化情况进行煤岩体裂纹扩展机理的研究，为进一步研究煤矿冲击地压的发生机理提供理论依据。
英文摘要：
Acoustic Emission （AE） and Computerized Tomography （CT） scanning are important means to monitor the coal and rock fracture propagation. The paper reviews the development of AE and CT tests and their application in coal and rock field. In light of the advantages of AE and CT scanning tests, it is proposed to jointly use AE and CT in the research of coal and rock structure, facilitating an effective combination of the research of coal and rock fracture propagation with the internal fracture change of coal-rock mass, and providing a theoretical basis for the further research of the occurrence mechanism of impact ground pressure in coal mines.
