余吾矿南五采区煤层顶板导水裂隙带高度预测研究
Study on height prediction of water flowing fractured zone of coal seam roof in South No.5 mining area of Yuwu Mine
摘要
Abstract
The mining of coal mine is bound to cause the movement and destruction of overlying rock mass.The height of water flowing fractured zone in fully mechanized mining face has become the key to establish hydraulic connection of overlying aquifer in coal seam mining,which restricts the safe mining of coal mine.Based on the geological and hydrogeological conditions of the thick coal seam mining area of Yuwu Mine of Lu'an Group,through the empirical formula calculation results,similar material simulation results and computer numerical simulation results,combined with the measured data of the water-conducting fracture zone in the working face of the adjacent mining area of the mine,the linear regression analysis of multi-data fusion was used to determine the height of the water-conducting fracture zone in the south fifth mining area.The value was 103.1~113.9 m,which provided scientific basis and parameters for the safety production and coal seam roof support of Yuwu Mine.关键词
