Base station communication method and device and mining intrinsic safety type communication system

The invention relates to a base station communication method and device and a mining intrinsic safety type communication system, and the method comprises the steps: obtaining a measurement report reported by a terminal, carrying out the analysis of the measurement report, obtaining the field intensity information in a downlink radio frequency signal received by the terminal, and when the field intensity information is smaller than a field intensity threshold value, adjusting the signal bandwidth of the base station to be a preset signal bandwidth value and keeping the number of resources allocated to the terminal unchanged, sending a command for indicating to increase the downlink gain of the base station, and controlling the total transmitting power of the antenna port of the radio frequency unit to be increased from the current transmitting power value to the maximum transmitting power value. Therefore, under the condition that the number of the resources allocated to the terminal is kept unchanged, the ave
