The invention relates to a storage chamber of a
high polymer material for blocking air leakage through spraying to a
coal mine. The storage chamber comprises a storage chamber body, an inner chamber is formed in the storage chamber, and the storage chamber is characterized in that a second temperature-
humidity sensor and a
flammable gas sensor are installed on a wall of the side surface of the inner chamber, supporting piers are separately fixed to the bottom surface of the inner chamber, and a bottom plate is fixed to the tops of the supporting piers; a heating groove is formed between the bottom plate and the bottom surface of the inner chamber, a heating
pipe and an air
pipe are installed in the heating groove, and the heating groove is filled with a phase-change energy-storing material; a dehumidifier is installed on the bottom plate, and an
electric control box is installed on the outer portion of the storage chamber. By arranging an
electric heating pipe and the dehumidifier, airin the inner chamber can be heated and dehumidified, therefore a good temperature-
humidity environment is ensured, and it is ensured that the stored material is in the environment with the best temperature and
humidity, so that it can be avoided that the material goes bad. The
flammable gas sensor can monitor
flammable gas in the inner chamber in real time, if the flammable gas exceeds the standard, gas in the inner chamber can be timely changed, and therefore the hidden safety danger is greatly reduced.
