So far

shaft-sinking by freezing is an effective method for coal mine construction

monitoring and researching temperature and variation rule in processing of freezing is of great significance for construction of shaftsinking by freezing and development of techniques. The basic principles of distributed fiber-optic temperature sensor is introduced

and application in Kouzidong project as example in monitoring of temperature of shaft-sinking by freezing in coal mine is also discussed. Compared with the performance of traditional single-bus temperature sensor in temperature measuring experiment

it is found that the distributed fiber-optic temperature sensor can realize continuous measurement for spatial in the case of the same temperature measuring precision

overcome disadvantages of traditional sensors

such as less measuring point and high fault rate. Experimental results show that distributed optical-fiber temperature sensor can play an important role in shaft-sinking by freezing in coal mine.
