文摘

Many factors and complexities are involved in breaking rock with conventional methods. Water jet technique is an effective solution to the problems faced in the conventional method. Rock deterioration is the most important step in the mining, civil, mineral engineering, the technology of water jet cutting and disintegration of various material attained continuous growth during the last decades. Water jet is widely used in industrial application such as disintegration of materials and rock, cleaning and removal of surface layers. The literature is reviewed the particular attention to the detection, recording and monitoring of fracture evolution, monitoring of collision healing and creep in rock and other material using acoustic emission. Acoustic emission has been widely used in industries and other various field such as steam pipes and pressure vessels, composites materials, monitor the welding and corrosion progress,metals and also applied numerous structural components. It is a technique to direct monitor defects formation and failure in structural materials. However, it can also provide information on the stress field, fatigue and the fracture pattern behaviour.
