Application practice of groove sampling method in oil shale open-pit mines
In order to more accurately and reliably reflect the occurrence status of oil shale ore bodies and rock masses,and to be more effectively applied in mining geological management,mineral processing management,and improving ore quality and production,this article combines the occurrence status of oil shale in the northern foothills of Tianshan Mountains in Xinjiang and the characteristics of open-pit mining of oil shale.The article introduces the application scenarios of groove sampling method in oil shale mining in detail,such as the selection of measuring lines,tool preparation,laboratory methods,sampling cost analysis,sampling quality assurance and safety measures.Based on the results of sampling and laboratory testing,the article discusses the methods for ore body delineation,drawing of measuring line bar and plane diagrams,and application examples of groove results.
