Little The Longtan Buzhaoba Open Pit Slope Safety And Economic Analysis

In pace with the expanding of human engineering activities and the rapid development of economy construction, the problem of predicting the stability of high and steep slope and the occurrence of large disastrous landslide become the forward position in the research of slope engineering. Both foreign and domestic researchers have researched extensively about the evolution regulation, stability and the slope landslide prediction and forecasting, established various models about the shape, characteristic, mechanical analysis, risk evaluation, treatment and inspection of slope, formed a series of theories, accumulated plenty of data and established a rather completed theoretical system.On base of a thorough investigation about the prototypical characteristic and the evolutional mechanical analysis corresponded to the reality, by using some basic material of BuZao Dam Open-Cut Mine in XiaoLongTan and the scientific and rational calculation method this thesis analyzes and calculates the slope stability of the northern and western bound which have the sliding tendency And talks about:1. the most possibility of large slope landslide in western bound, when it is cut down to the elevation of 970 meters.2. at the present situation, the stability of northern bound can't meet the need of safety mining, some adequate engineering measures are necessary for safety mining in BuZao Dam Open-Cut Mine.3. settlement plan:a) for safety mining, both western and northern bound surfaces should be cleaned up and the rock should be anchored by anchor ropes.b) anchor angle: the anchor ropes should keep at a 25-degrce--included angle up to the horizontal level,4. During calculation, this thesis also takes a comparative economy analysis, under the principle of "being sure of safety, the more economical, the better".
