Recently, CCTEG Xi'an Research Institute received a letter of gratitude from Zhenchengdi Mine of Shanxi Xishan Coal and Electricity Co., Ltd., which highly recognized its performance on the project "Quantitative Detection Technology Research of Geological Structures in the Driving Roadway of 28209 Track Feeder Chute".
In view of the complex geological conditions of the 28209 driving face, the expert team of CCTEG Xi'an Research Institute faced the difficulties head-on, rigorously formulated the detection plan, and strictly implemented the standardized underground operations. Relying on core technologies such as real-time seismic monitoring along with excavation and borehole geophysical prospecting, 17 geological abnormal areas were successfully predicted within the 605-meter driving monitoring range. A total of 844 meters of borehole geophysical prospecting was completed, and the comprehensive prediction accuracy rate exceeded 90%, effectively ensuring the safe production of the working face. After Zhenchengdi Mine adopted this technology, driving efficiency increased by more than 30%, significantly reducing time and labor costs. This technology helps Zhenchengdi Mine enhance its "three competitiveness" from the three dimensions of "reducing personnel, enhancing safety, and improving efficiency", providing a technical model for safe and efficient driving under complex geological conditions.
