| Blasting rock drivage footage is generally too low,making a summary analysis by the surveyquestionnaire and theory study,using systems theory and Interpretative Structural Modelingsystematic analysic surface,middle and deep influence factor of rock drift drivage,under thelinear programming perspective, establishing mechanized selection model of the drivage systemto provide technical scientific and technic support; making nonlinear relationship between rockdrift engineering features and monthly footage by BP neural network and MATLAB software,using gray relational degree to select input indicators for more accurate of model predictions,getting a more comprehensive rock drift construction effect evaluation index system, establishedAHP-fuzzy comprehensive evaluation model to quantify the evaluation of the rock driftconstruction effect, establishing benefit comparing models between general drivage and rapiddrivage and the advantage of benefit model for reducing construction time, and finally throughempirical studies had confirmed the correctness of the model to provide decision support andgiving powered support for coal enterprises doing the rapid drivage. |
