May 17，The "Shaanxi Provincial People's Government's Decision on Shaanxi Provincial Science and Technology Awards in 2022" is officially released，The "Geo-hole Electromagnetic Method and Three-dimensional Laser/Sonar Continuous Tracking and Precision Exploration Technology in Laoyao Goaf Area" project that Hanjiawan Coal Company participated in and applied for won the "Third Prize of Shaanxi Province Science and Technology Progress Award"。
In view of the complex distribution of goaf areas in old kilns、Accurate exploration is difficult、The reality that seriously endangers the safety of coal mine production，This project aims at precise exploration，Comprehensive utilization of ground transient electromagnetic detection technology、Three-dimensional transient electromagnetic detection technology in holes、Three-dimensional laser detection technology in the hole and peeking into the hole and related measurement methods，Constructed a precise exploration technology system for Laoyao goaf area，Achieved the detection of complex old kiln goaf areas (irregular distribution、Accurate detection of water accumulation or no water accumulation) and other hidden disaster factors with similar characteristics。
At the same time，This project proposes a new transient electromagnetic method of "ground-bore joint detection"，Improved the positioning accuracy of the goaf area of the old kiln；Developed three-dimensional laser and sonar scanning and modeling technology for the old kiln goaf area，Achieved precise exploration and three-dimensional visualization of goaf areas in old kilns with complex structures；The continuous tracking exploration technology of "joint ground hole detection + drilling + three-dimensional laser sonar scanning" has been formed，Fills the technical gap in the field of accurate exploration of goaf areas in old kilns with complex structures。
The coal industry development plan proposes to continuously improve safety and security capabilities，Promote the development of the accuracy of exploration of goaf areas in coal mines in the direction of precision。This project will promote precise management of goaf areas，Revitalizing the remaining coal resources in the goaf，Improving the comprehensive utilization efficiency of coal mineral resources is of great significance。
The heavy honor is affirmation，It is an inspiring motivation。Hanjiawan Coal Company will be guided by Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era，In-depth study and implementation of the spirit of the 20th National Congress of the Party，Further strengthen cooperation with outstanding scientific research institutions，Focusing on bottlenecks that restrict mine safety production，Carry out in-depth scientific research projects，Accelerate the transformation and application of scientific and technological achievements，Continuously improve the level of mine safety production，Strive to "rebuild a new northern Shaanxi mining industry"、Contribute to m88 best betting website to build a world-class energy group。(Zhou Zhufeng Guo Hongxin)
