Prediction of multiple linear regression analysis on water-conducting fracture zone development height in Chenghe mining area
By collecting the measured results of the height of water-conducting fracture zone in Chenghe mining area,we car-ry out a multiple linear regression analysis on the main controlling factors of the height of water-conducting fracture zone,which fitting the formula between the height of water-conducting fracture zone,the mining thickness of coal seam,the buried depth of working face and the length of working face inclination.The fitted formula is used to predict the height of water-con-ducting fracture zone on 1503 and 1506 working faces of Shanyang Coal Mine in Chenghe mining area.The predicted devel-opment height of water-conducting fracture zone on the working faces is basically consistent with the micro-seismic monito-ring results,indicating that the predicted value of water-conducting fracture zone obtained by the fitting formula is accurate,which provides a certain reference for the prediction of the height of water-conducting fracture zone on working face with similar geological conditions in Chenghe mining area.
