This invention provides a static cone penetration test (CPPT) system and method for measuring the thickness of carnallite ore layers based on an unmanned surface vessel (USV) with variable buoyancy anchoring. The system includes an USV body, a penetration unit, a main control unit, a data acquisition unit, a multi-parameter formation identification unit, and a fluid counterweight anchoring unit. When the USV body is not performing detection operations, the fluid counterweight anchoring unit increases the weight of the hull. As the static cone penetration probe penetrates the formation, it collects the end resistance at the probe tip and the frictional force on the probe sidewall sleeve, transmitting these data to the multi-parameter formation identification unit. The identification unit identifies the upper and lower interfaces of the carnallite ore layer. The control unit calculates the carnallite ore thickness based on the depth difference between the static cone penetration probes at the upper and lower interfaces of the carnallite ore layer. This invention improves measurement accuracy, resolves the contradiction between miniaturization and large reaction forces, does not damage the original crystallization environment of the salt lake, and enhances the safety of unmanned operations.
