Feasibility Assessment Algorithm for Land Reclamation in Abandoned Opencast Coal Mine Areas Based on Feature Fusion
Due to the susceptibility to ecological dynamic evolution characteristics during the land reclamation process in abandoned open-pit coal mining areas,the feasibility assessment results of land reclamation are not accurate.To this end,a feature fusion based feasibility assessment algorithm for land reclamation in abandoned open-pit coal min-ing areas was proposed.The probability integral method is used to evaluate the degree of land damage,analyze the dy-namic evolution process of land in the waste gas open-pit coal mine area,and integrate the characteristics of heavy metal pollution,land unit subsidence and horizontal movement,and surface subsidence.Introduce the principle of immune cloning model,construct a target fitness function,and clone an antibody library based on the affinity of im-mune cells and antigens.Based on the results of the cloning operation,evaluate the feasibility of land reclamation in the waste gas open-pit coal mine area,and evaluate the degree of heavy metal pollution in sediment using the land ac-cumulation index method.Based on the actual situation of the mining area,combined with principal component analy-sis method,evaluate the feasibility of agricultural,forestry,animal husbandry,and fishery reclamation.From the ex-perimental results,it can be seen that the different types of land reclamation spaces planned by this algorithm are con-sistent with the ideal results,indicating that the evaluation results of this method are accurate.
