我院修配厂研制的S D——1型复盖层钻机于83年9月至10月进行了首次野外钻探复盖层的试验,共完成三个钻孔达64米。 S D——1型复盖层钻机是一种带有多种功能的复合式钻探设备,具有振动、冲击、回转及液压给进等多种性能,可以形成单种功能或多种功能的钻进方法,为解决复盖层、杂复地层及基岩钻进提供了新的工艺手段。该钻机以机械传动为主,并辅以液压传动及操作,转速范围大,每分钟24～912转(18级),对大口径及小口径钻探部适用,回转
The SD-1 overburden rig developed by our institute was tested in the first field drilling overlay from September to October in 1983, completing a total of three bore holes of 64 meters. The Model SD - 1 Overburden Drilling Rig is a versatile multi-purpose drilling rig that performs a wide range of functions including vibration, impact, slewing, and hydraulic feed to create a single or multi-purpose drill Method, to solve the cover, complex strata and bedrock drilling provides a new means of processing. The rig is mainly mechanical transmission, supplemented by hydraulic transmission and operation, large speed range, 24 ~ 912 rpm (18) per minute, suitable for large diameter and small diameter drilling, rotary
