Yankuang Energy and Beidou Tiandi have obtained patents related to coal mine impact monitoring. Coal mine impact ground pressure monitoring helps support disaster emergency decision-making.

On March 28, news reported that the National Intellectual Property Administration’s information shows that Yancoal Energy Group Co., Ltd. and Beidou Tiandi (Beijing) Technology Co., Ltd. applied for a patent titled “A Monitoring Device and Method for Coal Mine Dynamic Pressure Based on GIS and MS Technology,” with the authorization announcement number CN115614103B, and the authorization announcement date being March 27, 2026. The application publication number is CN115614103A, the application number is CN202211424554.5, the application publication date is March 27, 2026, the application date is November 15, 2022, and the inventors are Qi Yuhao, Wang Jingyi, Wang Longjiao, Li He, Yu Tongzhu, Wu Jun, Zhao Xueqiang, Zhang Daixiang, and Du Gui. The patent agency is Xi’an Mingze Intellectual Property Agency (General Partnership), and the patent agent is Zhang Ju, with the classification number E21F17/18.

The patent abstract shows that this invention discloses a monitoring device and method for coal mine dynamic pressure based on GIS and MS technology, including the following steps: S01: Collecting basic data based on the MS microseismic monitoring platform; S02: Filtering and merging the collected basic data; S03: Performing numerical determination on the data through a dynamic analysis module and matching underground microseismic activities with a database; S04: Editing multi-parameter attributes of the analysis results and dividing regions based on different hazard levels; S05: Managing the energy early warning indicators of dynamic pressure events through a command management module and establishing prevention and control measures; S06: Establishing a self-learning model to continuously revise and improve the early warning model database. This invention can greatly eliminate the command delays caused by insufficient accuracy of the forecast location and inaccurate spatial relationship expressions, providing effective technical support for disaster emergency management and auxiliary command decision-making in coal mines.
