榆林大柳塔矿区乌兰木伦河径流量衰减的影响因素分析

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...

The regulators ofrunoff of the Ulan Moron River in the Daliuta mine area:The effects of mine coal

Based on the inspection, investigation and measurement of Daliuta mine area and Ulan Moron River and on the inheritance of existing research, this paper defines the major factors affecting the runoff in coal mine area, then it establishes the algebraic expression on the relation between coal mining and runoff and improves the multiple regression model by applying the finite distributed lag model. Then this paper analyzes the investigation data by applying the improved multiple regression model based on weighted least squares method. The results suggest that, among the factors, coal mining has an influential degree of 67.8% on the runoff attenuation of Ulan Moron River, of which surface subsidence and mine water discharge accounts for 39.5% and 28.3% respectively, while non coal mining factors have an influential degree of 32.2% on the runoff attenuation of Ulan Moron River, among which production and living water usage and natural factors account for 9.2% and 23.0% respectively.
