Dry-Hot Rock Potential of Changpu-Baimianshi District,Xunwu County
In order to explore the potential of dry-hot rock resources in the Changpu-Baimianshi district of Xunwu county,Jiangxi province,the geological background,geothermal geological characteristics and geophysical characteristics of this area are analyzed comprehensively.The dewpoint of geothermal hot spring and granite mass are sampled and tested.The volume method is used to estimate the dry hot rock resources in the favorable area.The results show that this area is located in the Nanwuyi Mountain uplift fracture banded thermal storage area,with large scale magmatic rocks and frequent intrusion activities.The average temperature of deep thermal storage is 112.47 ℃,the radioactive heat generation rate of rock mass is 4.4 μw/m3,and the estimated dry-hot rock resources are 4.35 billion tons of standard coal.The research shows that the dry-hot rock resources in the Changpu-Baimianshi area of Xunwu county have great potential,and further exploration and develo-pment are recommended.
