摘　　要：为了揭示榆横矿区南区开采地质条件,在对地质背景进行研究的基础上,以研究区大量地勘数据为基础,通过对瓦斯地质条件、水文地质条件、工程地质条件及其他地质条件的分析,开展了榆横矿区南区开采地质条件研究。结果表明:榆横矿区南区为瓦斯含量较低的瓦斯矿井;矿区水文地质条件为以孔隙裂隙含水层充水为主的水文地质条件中等的矿床;矿井工程地质条件属层状岩类中等型矿床;煤层具有爆炸危险性且容易自燃;矿区地温梯度正常,为无地热异常的地温正常区。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.
