ABSTRACT: With the depletion of coal resources due to
excessive exploitation and the increasing adjustment of the national energy structure,
in response to the call of national policy, some mines are forced to close, and
the reuse of abandoned mine resources plays an important role in the
sustainable development of mining industry. This paper analyzes the general
situation of abandoned mines in Huainan and Huaibei, elaborates the research
methods of geothermal temperature and calculation methods of geothermal
reserves in abandoned mines, analyzes and studies the utilization prospect of
geothermal resources in abandoned mines in Huainan and Huaibei, and draws the
following conclusions: the temperature of geothermal resources in abandoned
mines in Huainan and Huaibei is 25℃ - 60℃, which belongs to the moderate-hot water and warm water resources in
low-temperature geothermal resources, and can be used for geothermal heating,
industrial geothermal and entertainment industries. Based on the previous
experience in geothermal resource utilization mode, this paper provides theoretical
and technical support for the demonstration project of resource utilization and
development of abandoned mines in the Huainan and Huaibei mining areas.
