With the increasing number of deep mining operations,high temperature and heat damage has become a major problem restricting the sustainable development of mines.Especially in the deep development and exploration stage,the production must overcome the adverse environment of high temperature and high humidity in the single head tunnel,which seriously affects the physical and mental health of workers and the project progress.In view of the high temperature and heat damage challenge encountered in the production and exploration deep in Qinling Gold Mine,the suitable ventilation and cooling scheme to deal with high temperature and heat damage was determined by means of domestic and foreign research,theoretical analysis and scheme comparison.The scheme turns out to be ventilation system optimization,with Roots blower used for forced ventilation.Based on the practice in the levels of deep exploration,the test on forced ventilation scheme with Roots blower was studied through scheme design,resistance calculation and fan selection,in hope that it can provide technical support for deep exploration and underground mining in Qinling Gold Mine.
