| 摘 要： | 本文基于对地壳浅部地温场形成特征及控制因素的分析及对我国东部几十个矿区的地温测量和对若干典型热矿山的研究成果,提出改进的矿山地温类型划分,对原分类加以修订。新的划分系统分为两级,第一级为“类”,按矿区平均地温梯度值分为低地温(梯度)类、中常地温(梯度)类和高地温(梯度)类。第二级为“型”,按引起地温场显著变化的主要控制及致热因素,将低地温类型分为深源低热型、地下水循环冷却型;高地温类分为深源高热型、局部聚热型和附加热源型。这一新的划分基于广厚的资料基础,采取统一的划分原则,具有大的蓄容能力,较之原划分更符合我国矿山地温场的实际,因而对矿山地热研究实用意义更强。

| Abstract: | A new classification of geotemperature types of mine is worked out based upon the analysis of controlling and heating factors on geotemperature field of shallow crust and geother-mal surveying for tens of mine area, especially, the geothermal investigations ih a number of typical high temperature mines in eastern part of China.The new system considers two grades in the classification high grade is ascribed as "kind" and the low one is called "type". According to the average geothermal gradient in mine area, three kinds of geotemperature fields high temperature, middle temperature and low temperature are divided Then, according to the main controlling and heating factors causing the variety of geotemperature field, the temperature kind is further subdivided into several types. Thus the low temperature kind is subdivided into two low temperature types: one due to deep origin and one caused by cooling of ground water circulation. Mean while, under the high temperature kind, three high temperature types are identifed: one of deep origin, another one caused by local assembly of heat and the third one due to additional heat resources.Since the data base for this new classification is profound, adoptive classified principle is unified and it has a large compatibility. Therefore, the classification coincides with actual geothermal conditions of mines in China and it is of great significance for geothermal study of mines |
