摘　　要：王行庄煤矿位于河南省郑州市南45 km,设计生产能力120万t/a,为一大型新建矿井。该区因煤层埋藏较深、地温较高,地热成为影响该区煤炭开采的重要因素之一。通过对测温资料的整理,确定了恒温带、孔底温度、地温梯度和煤层底板温度等重要地温参数,并总结出矿区二1煤层地温变化规律、地温热害分区、地温梯度及地温异常分区、地温梯度变化规律、矿山地温类型等地温地质特征及其影响因素,并对矿区地热资源的利用进行分析。该研究对指导矿山建设与资源开发具有重要意义。Wangxingzhuang Coal Mine is located 45 km south of Zhengzhou, Henan Province, and the design and production capacity is 1.2 million t/a,whieh is a large new mine. Owing to coal seam is buried deeper,earth temperature is taller, so geothermal energy is one of the important factors affecting coal mining in this area. The temperature parameters of thermostatic belt, hole bottom temperature, ground temperature gradient and floor temperature of coal bed were determined through the arrangement of temperature measurement data in this area. The geological characteristics and their influeneing factors of the temperature change of coal seam, the land temperature and heat damage zone, the geothermal gradient and the ground temperature anomaly, the change of ground temperature gradient, the type of mine earth temperature were summarized. The utilization of geothermal resources in eoalmine was analyzed. This is of great significance to guide mine construction and resource development.
