Research of the Best Combination of Cooling Parameters in High Temperature Work Deep Stope
When designing cooling engineering in deep stope, the three parameters, air temperature, air velocity and distance between cooling air and work place, are three key factors to determine cooling effect. Lowering air temperature, increasing air velocity and shortening the distance between cooling air and work place can all achieve the purpose of cooling work place. Not only to achieve the purpose of cooling, but also to reduce operating costs, save energy and extend the service life of cooling equipments, these three parameters should be chosen and combinated rationally, to gain the fine operation conditions. Taking 7446 work face in Jiahe coal mine as an example, on the base of analysis of multiple sets of cooling parameters in a variety of conditions, it proposes the range of parameters which can gain better cooling effect, more economical run and longer cooling equipments service life. It provides a wider choice of reasonable parameters for 7446 work face cooling engineering.
