The invention relates to a production method of rock asphalt powder. The production method comprises the following steps: (S1) coarse crushing, namely crushing big rock asphalt ores into small rock asphalt ores, wherein the maximum sizes of the big rock asphalt ores are 25cm-50cm, and the maximum sizes of the small rock asphalt ores are 1cm-3cm; (S2) fine crushing, namely crushing the small rock asphalt ores into 14-35-mesh rock asphalt powder; (S3) drying, namely rapidly drying the rock asphalt powder at a superhigh temperature and a negative pressure; (S4) stacking, namely paving the dried rock asphalt powder in multiple storage bins in batch in a layer-upon-layer manner, wherein the rock asphalt powder in the same batch is uniformly distributed and is located on the same layer of each storage bin; and (S5) mixing and packaging: mixing and packaging the rock asphalt powder of different batches in the same storage bin for later use. By virtue of the production method, the production efficiency of the rock asphalt powder is greatly improved, and the defect of non-uniform effective content of a traditional stacking method is overcome.
