摘要（英）：

The invention relates to the field of underground ore drawing, and discloses a calibration device for an underground ore drawing test. The device comprises a calibration body (1) and an elastic expanding part (2) connected to the calibration body (1). The elastic expanding part (2) is in clamping connection with an inner wall of a hole in an ore rock, so as to enable the device to be fixed in the hole. Moreover, the elastic expanding part (2) can be unfolded relative to the calibration body (1), and the calibration body (1) is provided with an identification (3) which is used for marking the position where the device is located. The device is convenient to install, and is not liable to slide down after installation.
