Optimization method of ardealite-based cementing material for improving filling roof-contacted rate
The invention discloses an optimization method of an ardealite-based cementing material for improving the filling roof-contacted rate, comprising the following steps: adding ardealite powder and an excitant in different proportions into filling aggregate to prepare cemented filling body materials in different proportions; carrying out a cemented filling body strength test and a filling body expansion rate test on the cemented filling body materials with different proportions to obtain test data of the cemented filling body strength and the expansion rate of the cemented filling body materialswith different proportions; conducting stepwise regression analysis on the test data of the strength and the expansion rate of the cemented filling body through a quadratic polynomial; establishing aproportion optimization model of the cementing material by taking the 3d strength of the cemented filling body as an optimization target and the 28d filling body expansion rate as a constraint condition; and solving the optimization model to obtain the optimal proportion of the ardealite-based cementing material in the filling slurry. According to the design method, low-cost and high-value resource utilization of ardealite can be realized; and low-cost and high-value utilization of ardealite in filling mining can be realized.
