For the high-pressure flushing method, if the surrounding rock is impacted by a rock stratum with a soft upper part and a hard lower part, the surrounding rock can be rapidly degraded after being flushed by high-pressure water, and meanwhile, the surrounding rock on the upper layer can be disturbed, so that the problem of falling blocks and over-excavation in a larger area is caused.
