Abstract:-dimensional physical model of the gangue hill was constructed using Fluent software, and the internaltemperature field distribution law of the gangue hill was simulated and studied. The high temperaturearea was located under the side slope of the gangue hill. The ignition points were located at 7~10 m be⁃low the slope surface perpendicular to the slope and 9~11 m below the top. The temperature at the ig⁃nition points reached 438.7 ℃. The hole layout scheme was applied to the grouting treatment site of thegangue hill. Four rows of grouting holes were arranged in a plum blossom shape on the top of the ganguehill, with a row spacing of 3 m and a hole depth of 10 m. The results show that before grouting and ex⁃tinguishing work, this scheme can effectively reduce the grouting hazards and improve the treatmenteffect of grouting and extinguishing. Close-
