This invention belongs to the field of control, specifically an adaptive control method and system for the concentration of filling slurry in goaf areas. The method includes dividing a sequence into intervals, constructing a segmented calculation matrix, performing parallel calculations to obtain a hierarchical floating-point operation matrix, inputting the matrix into a slurry concentration estimation model, calculating predicted slurry concentration values ​​and concatenating them to form a concentration prediction sequence, performing differential operations on the concentration prediction sequence to obtain the concentration change gradient, and triggering a precision reconstruction mechanism when the absolute value of the gradient exceeds a preset threshold. This mechanism forcibly converts non-critical variables within the corresponding interval into a high-precision floating-point format, generates a reconstruction operation matrix, and re-inputs it into the model to calculate the predicted slurry concentration value. Based on the calculation deviation, a closed-loop feedback control algorithm is used to calculate the slurry water addition adjustment coefficient. This adjustment coefficient is then used to synchronously adjust the opening of the water supply valve and the slurry delivery rate, generating a slurry ratio control command, which is output to the filling control system to achieve coordinated flow regulation and ensure stable slurry concentration.
