矿产资源开采与水资源破坏相关性显著,因而定量分析开采的各类行为对水资源的破坏程度对干旱资源开发区具有重要意义.本研究应用有限分布滞后模型改进了多元回归模型,进而建立了煤炭开采与河流径流量相关关系的代数表达式,并利用其分析大柳塔矿区和乌兰木伦河的调查资料,进而说明煤炭开采是否是影响煤炭开采区河流径流量的主要因素.结果表明,在影响乌兰木伦河径流量变化的诸多因素中,自然因素占10.5%,人为因素占89.5%.在人为因素中,生产生活用水占12.2%,采煤活动占77.3%.在采煤活动中,矿井疏排水占24.8%,由煤炭开采导致的地表塌陷占52.5%.
Therefore, it is of great significance for the drought resource development zone to quantitatively analyze the degree of damage to water resources by various types of behaviors of mining.The improved multivariate regression model is applied in this study, and then a multi-regression model is established Coal mining and river runoff and use the data to analyze the survey data of Daliuta mining area and Wulanmulun river and then indicate whether coal mining is the main factor affecting river runoff in coal mining area.The results show that, Among the many factors affecting the flow change of Ulan Mulim River, natural factors accounted for 10.5% and human factors accounted for 89.5% .In human factors, production and living water accounted for 12.2% and coal mining activities accounted for 77.3% In the mine drainage and drainage accounted for 24.8%, caused by coal mining surface subsidence accounted for 52.5%.
