Lafarge Dujiangyan Cement Plant White By Om Mud Rock And Mineral West Side Of The Slope Stability Evaluation

Our country strip mine mining scale unceasingly expands, the mining depth unceasingly drops, gradually forms hollowly picks the field or deep concavely picks the field. Open-air slope design, finally slope angle the determination, slope work the and so on stable appraisal importance then day by day demonstrated, causes the strip mine slope stability problem to become a special research topic, the mountain body landslide which mine mining causes is at present picks moves one of in harm main disasters, picks moves the landslide not only to be able serious to damage the architectural engineering facility, causes the personnel casualty to create the huge property economic loss, moreover also can therefore the destruction forest vegetation, damages the farmland, forms the mud-rock flow disaster, intensifies soil erosion with wilderness degree. Picking the mountain body landslide disaster which moves causes in the world scope to arouse people's daily interest.This article in the scene investigation and study and in the acquisition of information foundation, the putty ore the side slope stability has done the system research to Dujiang weirs Lafaj base cement plant Bai Yi-an west. Its main content includes: (1) Comprehensively to studies the area the physical geography and the engineering geology environmental condition conducts the analysis research. (2) Through to the mining area west the side slope engineering geology condition research, obtains slope the structure characteristic and the crag body structure characteristic, as well as gneiss and structure surface physics mechanical properties. (3) Studies slope the distortion destruction characteristic, carries on the distortion origin analysis, carries on slope the distortion in this foundation to destroy the machine-made physical analogue, obtains slope distortion destruction pattern. (4) The opposite side slope stability carries on the analysis and the appraisal through the limit zero-method, moreover also discussed the intensity to fold the subtraction in this slope stable appraisal application. (5) Had pointed to this slope proposed the preventing and controlling government measure, and side preliminary slope synthesis angle.
