Abstract: In order to reveal the mining geological conditions in the southern part of the Yuheng mining area, on the basis of the
study of the geological background, based on a large number of geological exploration data in the study area, through the analysis
of gas geological conditions, hydrogeological conditions, engineering geological conditions and other geological conditions, this
paper carried out research on mining geological conditions in the southern area of Yuheng mining area. The results show that the
south area of Yuheng mining area is a gas mine with low gas content; the hydrogeological conditions of the mining area are
deposits with moderate hydrogeological conditions, which are mainly filled with water in pore and fissure aquifers; the engineering
geological conditions of the mine belong to the medium type of layered rocks; the coal seam is explosive and prone to spontaneous
combustion; the geothermal gradient in the mining area is normal, and it is a normal geothermal area without geothermal
anomalies.

Key words: southern area of Yuheng mining area; mining geological conditions; gas geology; hydrogeology; engineering geology
