On July 7, 2020, Zhang Liangfu, General Manager of Zhongrui Heavy Industry, and Mao Wei, Chief Engineer of Zhongrui Heavy Industry, and related technical personnel went to the headquarters of Anhui Hefei China Coal Third Construction Co., Ltd. to participate in the ZJD12000/1200 drilling rig design pre-acceptance review meeting.

Cheng Hua, President of Anhui University, Director of the Institute of Underground Engineering Structures, Yao Zhishu, Deputy Director of the Institute of Underground Engineering Structures, China Coal Third Construction Group Co., Ltd., and China Coal Special Shaft Sinking Co., Ltd. expert group participated in the ZJD12000/1200 drilling rig design The pre-acceptance review meeting focused on the overall layout and performance parameters of the drilling rig; electrical intelligent control; hydraulic system principles; drilling rigs, chassis, power heads, drill pipes, manipulators and other important steel structure components and finite element analysis of steel structure components communicate with. After two days of detailed and in-depth discussion, the pre-acceptance review meeting for the design of the main engine of the ZJD12000/1200 800m high-efficiency intelligent vertical well drilling rig for deep water-rich rock formations was successfully concluded.

In May 2020, Zhongrui Heavy Industry was commissioned by China Coal Third Construction Group Co., Ltd. to be responsible for the design of the "800m deep water-rich rock formations with high-efficiency and intelligent shaft drilling rig main engine". The project was officially launched on May 7, 2020. As the country's first super-large-diameter intelligent vertical well drilling rig, the acceptance of this project is a milestone for the company's development. In the past two months, all the staff of the technical department focused on the project, worked together to overcome difficulties, ensured the quality of the design, kept a close eye on the time node, and made every effort to ensure the progress of the project, laying a solid foundation for the equipment manufacturing and project application of the project.
