The invention discloses a dynamic weighing calibration method for remote monitoring of mining yield. The method comprises the following steps: firstly, sampling and processing signals to convert a weighing signal into a digital signal, and drawing an oscillogram by taking time as the abscissa and the signal strength as the ordinate; then processing the obtained oscillogram in segments, computing a dynamic speed S of a weighed object as speed compensation for computing a measured value, and computing a vibration frequency F of the oscillogram while the weighed object is put on a weighing machine; and regulating the sampling frequency of the next time according to the vibration frequency and a Nyqouist sampling theorem; finally, computing the measured value according to data of the oscillogram. In the method, the measured weight value of the dynamically weighed object is corrected by taking into account a plurality of influencing factors to cause the measured value to be much closer to the actual weight of the weighed object, thus achieving accurate measurement and monitoring of the mining yield.
