中文摘要：
导水裂隙带高度是矿井生产中影响安全生产的一个最重要的影响因素之一;另一方面,多元统计分析和敏感度分析在工程数据分析中应用广泛.以多年来我国矿井生产中实测的数据为基础,应用多元统计分析建立了导水裂隙带高度与采厚、采深和硬岩岩性比例系数的函数关系,用敏感度分析的方法确定了各个影响因素的敏感度,进而建立了DM-L优化模型.最后对模型进行了检验,结果显示模型精度较高.
英文摘要：
One of the most important factors for ensuring mine production safety is to predict the height of water flowing fractured zone.Multivariate statistical analysis and sensitivity analysis were be used generally in engineering data analysis.A functional relationships among height of water flowing fractured zone,mining thickness,mining depth and coefficient of hard rock lithology ratio were constructed by applying multivariate statistical analysis and the foundation of substantial data,which are from mining production during recent years.Using method of sensitivity analysis to determine the sensitivity of each influencing factor,therefore,DM-L optimization model be established.Tested the model,a higher accuracy of the result be responded in the end.
