... in ore bodies and the pressure and flow of water injection. Five sensors of four different types are used in the test. Each sensor uses independent acquisition software. The operation is cumbersome and complex, and data synchronization is difficult and can be easily lost. Therefore, an integrated data...

.... Then, based on the arrival time of the MS source, combining the sensor array and the expression of the TM-PSO method, the convergence and correlation of objective functions of the TM-PSO method are analyzed theoretically. The field test of the Beiminghe iron mine in Hebei province and the headrace tunnel...
