HEIGHT OF HYDRAULIC FRACTURE ZONE BASED ON PSO_LSSVM MODEL

Height of Hydraulic Fracture Zone Based on PSO_LSSVM Model

Predicting the height of water conducting fracture zones can prevent mine water damage and increase the upper limit of mine mining.To achieve its effective prediction, this study selects four main control parameters for prediction, including the proportion coefficient of hard rock in the overlying strata, the inclination distance of the working fac
