Fine Modeling and Virtual Reality Platform Construction of Shuangyang Coal Mine Based on Multi-Source Data Fusion
Aiming at the current situation of the low mining height of extremely thin coal seam working face,difficulty in equipment selection and low working safety factor,combined with the backward problem of intelligent mining technology in Shuangyang Coal Mine,the efficiency of thin coal mining was improved and the production safety risks was reduced by establishing a multi-source data-driven refined geological model and a virtual reality platform.Firstly,multi-source heterogeneous data of mines such as borehole and 3D seismic was acquired,analyzed and classified.Then,based on path cutting algorithm,distance weighted interpolation and other means,a comprehensive geological model of extremely thin coal seam was established,which integrated roadway,fault,mining area,coal and rock stratum and working face.Finally,a virtual reality cloud platform was built,combined Unity3D development engine and WebGL technology,the constructed 3D visualization model was rendered and released,and the monitoring arrangement of environment perception,ventilation,ground pressure and other data in the refined model was carried out.At the same time,in order to take into account the convenience of acquiring underground construction data,the mobile phone platform was used to enhance the timeliness of information management.The results show that the proposed fine modeling and visualization platform in Shuangyang Coal Mine can improve the transparency of the working face,the intelligence of mining,the digitization of risk warning,and the informatization of production management.
