The invention relates to the technical field of mining and provides an on-demand heat supply system for a mine. The system comprises ventilation equipment, a mine on-demand ventilation device, a return air waste heat collection device and a heat supply controller; the mine on-demand ventilation device is connected with the ventilation equipment to control the ventilation equipment to work; the return air heat collection device collects heat in mine return air in an air passage; the heat supply controller calculates a waste heat collection amount of the return air heat collection device according to control data of the mine on-demand ventilation device for controlling the operation of the ventilation equipment and determines a newly added heat supply amount according to the waste heat collection amount and a preset heat supply plan. According to the system, the waste heat collection amount is calculated according to on-demand ventilation conditions of the mine, and the newly added heatsupply amount is determin
