Research on Accurate Three-Dimensional Modeling Technology and Intelligent Mining in Coal Mines

This article presents the background and demand for intelligent mining at the Buertai Coal Mine, operated by China Shenhua Shendong Coal, and addresses the challenges faced in geological condition identification during the construction of intelligent workfaces. To tackle this issue, the mine conducted comprehensive geological studies, with a focus on establishing a three-dimensional geological model of the working coal seam. The research involved collecting geological data from the workface, seismic tomography exploration, borehole permeability exploration, and other methods. By utilizing a discrete smoothing interpolation algorithm, accurate calculations were performed for the elevation of the roof and floor of the workface, leading to the development of a static three-dimensional geological model. During the dynamic modeling phase, the static model was continuously adjusted using real-time geological data, resulting in a dynamic model that reflects the workface’s geological conditions more accurately. Finally, based on the established three-dimensional geological model, an entity model was constructed and presented, providing real-time geological parameters for intelligent mining. The article also introduces a method for predicting the elevation of the roof and floor using the discrete smoothing interpolation algorithm, and validates its effectiveness through experiments. In summary, this research provides essential transparent geological support for intelligent mining in the coal mine, and it holds practical application value.
