Microwave thawing of frozen coal

摘要

Thawing frozen coal is always among the most severe obstacles faced by northernmost regions of the world,which needs to be solved urgently because frozen coal cna have a bad effect on the production of these regions,especially power palnt.After several years of research,an applicable method for thawing coal is put forward.Also,the method for measuring attenuation constant of coal,together with its variation pattern is illustrated.The experiment results show that microwave thawing of frozen coal is an effective way to solve the problem.
