Prediction Based on BP Network for Coal Mine Paste Filling Material Strength

Article Preview

Aiming at the factors affecting the strength of coal paste filling material, the relation between affecting factors and strength of coal paste filling material was revealed on the basis of a lot of experiments in the lab, in which the river sand was used as skeletal material. The tests show that the strength is mainly affected by the slurry density, dosage of fly ash and cementation. However, the establishment of mathematical model between the strength and all affecting factors is very difficult. In order to more accurately forecast the strength of coal paste filling material, the model was established by applying BP networks. The results show that the model is feasible and scientifically justified to forecast the strength of coal paste filling material. The conclusions can provide some references for the practice of none-village-relocation coal extraction in the mine. Introduction
