Analysis and control of deep high temperature heat damage in Jiangjiayao Gold Mine

High temperature heat damage in mines is a key factor restricting deep mining.This article takes the Jiangjiayao Gold Mine as the background, and based on on-site research, analyzes the existing thermal hazard characteristics and mine heat sources in the mining area.Based on the heat source analysis results and on-site monitoring data, the independently developed airflow parameter prediction software was used to predict the airflow parameters of the horizontal roadway in the undeveloped layer.The results show that the thermal environment parameters in the undeveloped area were generally controllable, which can provide reference for the design of the ventilation system in the later stage.In addition, based on the treatment measures for thermal hazards in deep mining of similar mines both domestically and internationally, as well as the characteristics of thermal hazards in the Jiangjiayao Mining Area, suggestions for the optimization and construction of ventilation systems in the later stage have been provided.The research results of this article can provide reference for the research and treatment of deep thermal damage in similar mines.
