Treatment Technology for Heat Damage in Deep Mine

To solve the problem of thermal damage caused by the increasing of coal mining depth and mining mechanization level, Daqing Coal Mine uses integrated mine thermal damage treatment technique, including increasing air volume, avoiding local heat source, pre-cooling intake airflow, isolating from high temperature surrounding rock, adopting individual protection and mechanical refrigeration, to solve the problem that thermal damage seriously affects mine safety and efficient production, and to ensure the staff's physical and mental health at the same time. Through the thermal damage treatment of deep shaft in Daqiang Coal Mine, we fish out mature deep mine thermal damage treatment technology.
