Recently, the 3rd World Smart hashtag#Mine Conference, sponsored by the China Coal Society, was held in Qingdao, Shandong Province. At the conference, the "Xiaowu" Geological Vertical Large Model project submitted by CCTEG Xi'an Research Institute won the Silver Award for Innovative Achievements, de

Recently, CCTEG Xi'an Research Institute completed the delivery of equipment for the remanufacturing project of hashtag#directionaldrilling rigs and mud pump trucks at Xiaobaodang hashtag#Coal Mine of Shaanxi Coal Group. This project is a technical service provided by CCTEG Xi'an Research Institute,

In hard rock drilling, few design variables influence performance as directly as the arc angle on a PDC bit's cutters and blades. When practitioners ask how arc angles vary for different formations, they are ultimately asking: how should we shape and orient the cutting structure to maximize rate of penetration (ROP), maintain toolface stability, and minimize wear, while preserving directional control and borehole quality?

In modern oil and gas, geothermal, mining, and construction drilling operations, productivity hinges on the durability and performance consistency of the polycrystalline diamond compact, or PDC bit.

Recently, the research and demonstration project of overburden separation grouting and backfilling technology with hashtag#coal gangue in Buertai Coal hashtag#Mine, approved and initiated by the National Energy Group and undertaken by CCTEG Xi'an Research Institute, has successfully passed the dual
