摘要
通过收集澄合矿区多个工作面导水裂隙带高度实测结果,采用多元线性回归分析的方法分析导水裂隙带高度的主控因素,拟合形成导水裂隙带高度与煤层开采厚度、工作面埋深、工作面倾向长度之间的各相关公式.采用拟合公式计算澄合矿区山阳煤矿1503、1506工作面导水裂隙发育高度,计算得到的工作面导水裂隙带发育高度与微震监测结果基本吻合,表明拟合公式获得的导水裂隙带估算值较为准确.在澄合矿区应用性较好,为澄合矿区相似地质条件的工作面导水裂隙带高度预测提供一定的参考依据.
Abstract
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.
