现将我队在50号金伯利岩管东部施工的5058-2、5060-2、5059三个孔的纠斜经验介绍如下地层与孔斜情况本区金刚石矿体为基性-超基性岩体.矿体走向近东西,向南倾斜,倾角80～85围岩有石英砂岩、粉砂岩、砂质页岩等,可钻性6～10级岩层走向近南东,向东或北东方向倾斜,倾角10～30.由于地层的促斜作用,从南往北打的钻孔倾角下垂:从北往南打的钻孔倾角易上漂顶角变化每百米1 30’～3左右,不论钻孔向南或向北施工,方位角都是向西偏移而平行矿体走向,难以
Now my team in 50 East Kabeili No. 5058-2, 5060-2, 5059 construction of the three holes described the experience of the following stratum stratum and hole inclination of the area of diamond ore body is the basic - ultramafic rocks . The orebody goes to the east and west and is slanted to the south with quartz rock, siltstone and sandy shale on the surrounding rock of 80 ~ 85 ° dip angle. The rock formations with drillability of 6 ~ 10 go southward and eastward or northeastward , Dip 10 ~ 30. As the formation of the role of oblique, drilling from south to north play dips angle dip: from north to south to play the drilling angle prone to drift angle of about 30 ~ 30 per 100 meters, regardless of Drilling to the south or north to the construction, the azimuth are offset to the west and parallel to the ore body, difficult
