无损检测(NDT)技术是煤矿机械安检的重要手段。通过采用无损检测的方法对大型在役设备的重要承载部件进行检测能够有效预防主轴开裂、风机叶片断裂等机电事故,确保煤矿的安全生产。在煤矿机械安检中应将无损检测技术予以推广。 Nondestructive testing (NDT) technology is an important means of coal mine machinery security. Through the use of non-destructive testing methods for large-scale in-service equipment for carrying important components can be detected effectively prevent cracking of the main shaft, fan blades and other mechanical and electrical accidents, to ensure the safe production of coal mines. Non-destructive testing techniques should be promoted in coal mine machinery security inspection.
