低温岩层预冷入风流技术研究与应用

摘要

随着矿井开采深度的增加，井下的热害日趋严重，尤其对于深井条件下，降温工作就成了安全工作极为重要的内容。本文阐述了低温岩层预冷入风流技术的试验研究成果，在采用通风降温技术的过程中，结合该项成果的应用，明显地改善了深井通风的降温效果，降低了通风降温工作的成本，取得了较好的技术经济效果。%With the increase of mining depth,the underground heat harm becomes more serious.Especially for deep shaft conditions,the temperature lowering has become a very important content in safety work.The paper describes the experimental research achievement of the precooling technology of downcast air for low temperature rock stratum.The applicaton of this achievement in ventilation and temperature lowering process can obviously improve the temperature lowering effect in deep mine ventilation and reduce the cost so as to achieve both good techhical and economical effects.
