官方解释性注释以英文显示。
说明
This division includes specialised support services incidental to mining provided on a fee or contract basis. It includes exploration services through traditional prospecting methods (for example, taking core samples and making geological observations as well as drilling, test drilling or redrilling for oil wells, metallic and non-metallic minerals). Other typical services cover building oil and gas well foundations, cementing oil and gas well casings, cleaning, bailing and swabbing oil and gas wells, draining and pumping mines, and so on.
