Abstract
The standard drill pipe for drilling in coal mine gallery is one of the main drilling tools in underground coal mine drilling. Its reliability directly affects the safety and efficiency of drilling construction. This paper describes the detection method of static torque of standard drill pipe for drilling in coal mine gallery, including detection principle, equipment used, detection method and process, and detection data analysis, which provides basis for the design, testing and inspection of the standard drill pipe for drilling in coal mine gallery, ensures that the standard drill pipe for drilling in coal mine gallery can be used within the torque range it can bear, and provides a safe and reliable guarantee for drilling construction.
