Get channel from reflect.SelectCase

If I create an array of reflect.SelectCase

for i := range workers {
        cases[i] = reflect.SelectCase{Dir: reflect.SelectRecv, Chan: reflect.ValueOf(channels[i])}
}

Inside function like this:

func (cases []reflect.SelectCase){
    for i := range workers {
        cases[i].getChan <- struct{}{} // ??
    }
}

How can I get chan to send value?
