The coring system YPK 36-I used widely at present in underground diamond drilling has advantages of reasonable structure, reliability and long life.This paper discusses specially following problems involved in coring systems: thread design and steadiness of steel and aluminium string of drill rods, structure principle of the swivel type double tube core barrels, inseparable head assembly, design speciality of ribbed core lifter case, and reasonability problem of the relation between the dimensions of inner and outside tube and the diamond bit used for 36ram size in China. The details and problems in the using of this system are introduced here. An idea of designing a coring system for formation which is difficult to drill,a coring system without lifting drill rods and a coring system with thin walled pipes is presented by the author for meeting the need for the development of the underground drilling.

目前在坑内金刚石岩心钻探中大量推广使用的YPK36-I型钻具,具有结构合理,性能可靠,寿命长等一系列优点。本文着重讨论了钻具所包括的钢、铝钻杆柱螺纹设计和强度问题,双层单动岩心管的结构原理,整体式异径接头,肋管式卡簧座的结构特点,以及我国36mm口径所用的内外岩心管规格及钻头规格匹配的合理性问题。本文还介绍了该钻具在使用中的情况及存在问题。为了适应坑道钻进日益发展的需要,提出了研制难取心的地层钻具、坑内不提取钻心钻具及薄壁管钻具的设想。
