The present invention relates to a long-period-storage coal pile heat value measurement coal sample pre-embedding device belonging to the technical field of coal pile heat value measurement. The long-period-storage coal pile heat value measurement coal sample pre-embedding device includes an outer drilling protective casing and an internal coal sample storage unit; the outer drilling protective casing includes a drilling circular pipe, a front end cone tip, pipe wall circular holes and a drilling handle; the front end pipe wall of the drilling circular pipe is provided with the plurality of pipe wall circular holes, the front end cone tip is installed on the top of the circular pipe, and is used for reducing resistance during a drilling process; the rear end of the drilling circular pipe is provided with the drilling handle; the internal coal sample storage unit includes U-shaped channel steel, coal sample storage cells, strip-shaped cover plates, nuts, coal sample storage cell surface circular holes and partitions; the front end of the U-shaped channel steel is provided with the plurality of coal sample storage cells, the coal sample storage cells are separated by the partition, the upper parts of the coal sample storage cells are covered with the strip-shaped cover plates, and bolted. The device can reduce the sampling error to the greatest degree, reduces the number of times of sub-sample collection, and can make a test task simple.
