Zusammenfassung:The invention discloses a VCR mining method using a novel blasting mode, and relates to the technical field of mining. The VCR mining method comprises the following steps of (1) performing stope arrangement, (2) performing cutting engineering, (3) performing medium-length hole blasting, (4) performing VCR method deep hole blasting, (5) performing hole measurement, (6) performing hole plugging, (7) performing charging, (8) performing line connection, and (9) performing ore removal. By means of the steps, the effect that shock waves and seismic waves fail to strike the earth surface is achieved, and no harm is caused to common brick houses and non-anti-seismic large building block buildings on the earth surface; the explosive unit consumption q is about 0.33 kg/t according to the bench height of each charging, the ore caving amount per meter of the designed deep hole and the total explosive amount consumed each time; and the method can improve the production efficiency, the blasting vibration is small, the seco
