湖南省干热岩资源类型研究

Study on the Hot Dry Rock Resources Types in Hunan Province

本文根据已有调查研究及样品分析测试数据,进一步对湖南省区域构造背景、岩浆岩分布、地热显示,以及岩体的热物理性和生热率等特征进行了详细描述,结合国内外干热岩资源类型特征,将湖南省干热岩体的资源类型初步划分成构造岩浆余热型、放射性生热型以及综合型三类。其中,骑田岭等岩体为放射性生热型,沩山等岩体为构造岩浆余热型,东岭岩体为综合型。

Based on the existing investigation and sample analysis and test data,this paper further describes the regional tectonic background,magmatic rock distribution,geothermal display,thermal physical rationality,heat generation rate and other characteristics of the rock mass in Hunan Province.Combined with the characteristics of hot dry rock resource types domestic and overseas,types of the hot dry rock in Hunan Province are preliminarily divided into structural magmatic residual heat type、radioactive heat generation type and comprehensive type.Among them,Qitianling and other rock bodies are of the radioactive heat generation type,Weishan and other rock bodies are of the structural heat recovery type,and Dongling rock bodies are of the comprehensive type.
