The traditional detection methods for the overburden failure parameter are difficult

high cost and low precision

such as simple hydrological drilling fluid analysis

drilling pressure and water injection experiment.A new dynamic monitoring system of overburden failure parameter in working face using network parallel electrical instrument

mine ethernet and ground remote terminal is introduced.The detailed system composing configuration and the layout method of underground sampling section are given.On the basis of experimental data obtained from practical application

the overburden failure parameter is provided.The system can record the dynamic development process of overburden failure with mining

and it has guiding significance on safety production in coal mine.
