QZ35型潜入式竖井钻机是在地面动力式钻机某些成熟经验的基础上,为适应钻全井需要而研制的一种新型钻机.它由山东省煤炭科学研究所和冶金部马鞍山矿山研究院等单位共同研制.主机结构分表土层钻头和岩石层钻头两种形式.1982年初,表土层钻头(图1)已在兖州矿务局南屯煤矿完成了第一口井筒钻进的工业试验,钻井直径6.2米,井深111.2米.岩石层钻头目前尚未制成,故本文仅介绍表土层钻头. QZ35 submersible vertical shaft drilling rig is a new type of drilling rig developed to meet the needs of drilling the whole well based on some mature experiences of ground dynamic drilling rigs.It is composed of Shandong Institute of Coal Research and Maanshan Mining Research Institute of Metallurgical Department In the early 1982, topsoil drill bit (Figure 1) had completed the first wellbore drilling industrial test at Yanzhou Mining Bureau Nantun Coal Mine, drilling 6.2 meters in diameter and 111.2 meters in depth.The rock drill has not yet been made, so this article only describes the top drills.
