Coal face wireless sensor network is helpful in environmental monitoring and automatic control of mining equipment,and wireless communication is a key factor affecting the coal face working performance of wireless sensor networks.This paper firstly proposed coal face wireless sensor network system structure,then analyzed communication loss factors in underground wireless such as coal-rock structure,machine noise and other factors,built coal face wireless communication channel model.Finally made model simulation analysis,and compared with measured data,results show that the model matches measured data well,which built foundation for coal face wireless sensor network.
