坑道钻探在贵州省精确探矿中的关键技术研究
Research on key technologies of underground core l drilling for the precise exploration in Guizhou province
摘要
Abstract
In recent years,Guizhou Province has vigorously promoted the"precise exploration of rich ore deposits"project,where many drilling holes need to be achieved through inclined holes in tunnels.This paper takes the underground core drilling at Lijiawan manganese mine as an example to address the problem of large azimuth errors in inclined holes in tunnel.Multiple techniques are comprehensively used,directional drilling and correction techniques are applied to wireline coring through drilling rig selection and drilling technology research.With the coordination of inclined tools and measurement systems while drilling system,real-time monitoring of drilling hole azimuth,inclination angle and other parameters is carried out using hole bottom-hole guidance devices.The drilling trajectory was controlled precisely and a series of valuable results have been obtained,which further verify the significant effectiveness of underground core drilling technology in precise exploration,demonstrate the characteristics of high drilling efficiency,precise hole inclination control and good coring integrity,and has the value of promotion and application.关键词
