Method and device for increasing distance between ore blocks in sorting process

The invention relates to the technical field of mineral separation, in particular to a method and device for increasing the distance between ore blocks in the sorting process. The method comprises the steps that ore blocks are placed on a horizontal conveying belt and conveyed to an end point; the method comprises the following steps: firstly, an ore block falls along a tangent line from an end point, a signal sent by the ore block and the shape of the ore block are detected, whether the ore block is removed or not is judged through logic calculation and a given choice value, and if it is judged that the ore block is removed, a removal signal is obtained; if it is judged that the ore blocks are reserved, a reservation signal is obtained; transmitting the removal signal or the retention signal to an execution mechanism; if the executing mechanism obtains the removal signal, the executing mechanism is started, force is applied to the ore blocks, the movement track of the ore blocks is changed, and the ore block
