Abstract:TheLaoyacha gold mine mudslide niche is at the river south works properly Laoyacha
brain in treasure City on taking, the its mineral mountainous country quality environment problem is miniaturing of the whole little Qin Ling the gold mine area geology environment problem.This text only chooses to appease swollen mountain stream and mire stone be in transit of block the residue dam prevention and cure engineering to carry on elaborating.Pass to carry on comparing to choose to the different dam type structure project, recommend Wu work deeply water comb a Chi dam to choose a project for design, and to the discharge of Hong Feng, block the residue dam dam crest to overflow to flow over the discharge, block a residue dam stability to carry on to check calculate, completed to manage an engineering design.Should manage engineering to always invest 3,000,000 dollars, make the geology environment of the mineral mountain parts of districts can initial instauration, manage engineering to have the aggressive demonstration the function to the little Qin Ling Gong3 area environment.
Key words:Debris Flow ；manage ;block a residue dam;geology environment;model function
