The ZK1814 hole of Zhuxi Mining Area Deep Exploration Demonstration Project contracted by the First Team of the 912 Geological Brigade of Jiangxi Provincial Bureau of Geology and Mineral Resources successfully ended the hole. The hole was designed to have a depth of 3000m, started drilling on October 27, 2017, ended the hole on October 10, 2018, with a diameter of φ122mm and a depth of 2430.35m, and ended the hole in advance under the condition of meeting geological requirements. There are thick coal measures strata in the periphery of Zhuxi mining area, and from time to time, steep metamorphic rock strata will be encountered, and drilling deviation is easy to occur in drilling construction. In order to achieve better geological results, the geological department is the requirement of the whole hole rope coring, drilling accuracy

The ZK1814 hole of Zhuxi Mining Area Deep Exploration Demonstration Project contracted by the First Team of the 912 Geological Brigade of Jiangxi Provincial Bureau of Geology and Mineral Resources successfully ended with a design depth of 3000m and 2017 m.Drilling was started on October 27, 2018, and the final hole was finished on October 10, 2018.
