肖家沟9#矿渣堆泥石流基本特征及防治建议

Basic Features and Control of the Debris Flow from Slag Heap 9 in the Xiaojia Gully

肖家沟9#矿渣堆位于泸州叙永县落卜片区硫铁矿矿区,为一条由矿渣形成的潜在泥石流,威胁沟口厂矿企业和沿沟耕地。实地调查和勘查发现,肖家沟泥石流发育主要受沟道条件、物源条件、水源条件的影响。通过深入分析该泥石流基本特征值基础上,提出了通过对堆积体采用稳拦工程,进而实施堆积体土地复垦的防治建议。

The Xiaojia Gully is located in a pyrite mine district in Luopu,Xuyong County,Luzhou.It is a flow gully with potential debris formed from slag heap9,threatening gully factory and mining enterprises and cultivated land along the ditch.A field investigation indicates that the development of the possible debris flow will be influenced by channel conditions,material conditions and hydrogeological conditions as well as the existing engineering project.A suggestion on its control was made based on the analysis of possible movement characteristics of this debris flow.
