Fast and Accurate Prediction Method of Ordovician Lime Water Inrush in Coal Mine Based on CUDA Parallel Computing
By analyzing the current situation of water inrush prediction research in our country's coal mines, this paper points out that the water inrush prediction method in coal mines is difficult to achieve real-time monitoring of water inrush risk under the current conditions. The author conducts finite element analysis of the area to be monitored, and inversely calculates the water level of each node in the monitoring area according to the water level of boreholes in the area, aiming to predict the risk of water inrush. Combined with the above-mentioned finite element water inrush prediction method, the author applies CUDA parallel computing technology developed by Nvidia to the preven-tion and control of water inrush in coal mines. This paper introduces the idea and model of CUDA water inrush prediction software in detail. The CUDA monitoring water inrush program is compiled and the actual prediction of water inrush points in the coal mine is carried out in combination with the drilling water level data. Compared with the traditional CPU serial calculation, the calculation speed of water inrush prediction in the coal mine is greatly improved, which has reference signifi-cance for realizing fast and accurate prediction of water inrush in coal mines.
