Controlled Directional Deep Hole Drilling in The Sharp Slanted Orebody at Duobaoshang Tongshan

摘要:

在老矿区勘探时，针对新布置的钻孔大多数是两老孔中间的加密孔或后排孔这一特点，给出了新布置钻孔轴线的设计方法以及采取的造斜、纠斜技术措施，取得了较好的效果

Abstract:

Most of the newly located holes for the exploration of the old mines are infilled between or lie behind two existing holes. In the light of this feature, the design method of the axis of the newly positioned hole is presented with the kicking off and deviation correction measures, resulting in good effect.
