The utility model discloses a top plate pressure detector during the period of passing through an air oxidation zone, and relates to the field of peroxide zone detection. The top plate pressure detector comprises a top plate structure, a supporting structure and a pressure detection structure, the supporting structure is slidably clamped below the top plate structure, and the pressure detection structure is fixedly arranged between the supporting structure and the top plate structure. According to the top plate pressure detector during the period of passing through the wind oxidation zone, the detector body is directly contacted with a rock stratum above the supporting plate through the sensing block, so that on one hand, the detector body can directly sense the pressure change of the rock stratum through direct contact; on the other hand, the shape change of the supporting plate caused by the stress change of the rock stratum to the supporting plate in the nearby effective range can be sensed through the con
