【摘要】 介绍了声波CT层析成像技术的探测设备、基本原理、观测系统的建立和资料的处理.并介绍了其在新桥硫铁矿的应用情况,得出了岩溶主要分布在-80m以上,声波速度在1200～2800m s区域内的结果.实际应用表明,应用声波CT层析成像技术可以准确地探测出岩溶、裂隙的分布情况,其结果为二期扩建工程注浆帷幕的设计提供了有力依据.图3,参10.更多还原

【Abstract】 In this paper,the equipment, principle, technology and readout of computerized tomography are presented. Also it’s application in Xinqiao Pritres Mine is introduced. The result, which karst mainly locats in the area that is over -80m and velocity of sound wave is between 1 200m/s and 2 800m/s is gained. It is proved to be a good technology in karst prospecting with its application. According to the results of prospecting, the parameters of slurry-injection purdah is correctly designed.3figs.,10refs.更多还原
