Research on improving the environment of tunnel using mine geothermal effect

Yongliang Zhang, Di Wu and Zhi

Abstract

In order to rational use geothermal effects, analyzed seepage from rock fracture and stress relationship，built model of heat and moisture exchange between inlet airflow and low temperature rock layer, Based on Jiudian Gold original main inlet air system, designed the upper abandoned roadway as mine inlet air cooling space, measured pre-cooling effect on the spot, results show that: using mine shallow geothermal effect can regulate the inlet air temperature effectively, improve working environment.
