Study On Stability Analysis Of Copper And Sulfur Ore Open-pit Mining Of Chengmenshan South Slopes

With the development of world science and engineering, human transformation ofnature is bound to spark friction between with its original topography.People with thewidespread nature of the rock geotechnical opportunities will deal more and more so forthe understanding of the geotechnical rock is especially important.People in theunderstanding of the nature after the study concluded discovered rock slope stability,reservoir induced earthquakes, underground factories, tunnels, dams and other miningprocess stability and the stability of the cavern with water issues, etc. are involved inconflict to study the mechanical properties of rock and soil water.Engineering practiceunder the urgent need for a systematic study of human or natural disturbance, theinteraction between rock or soil and water, and its impact on the stability of practicalengineering problems.In this paper, the impact of rainfall in different types ofgeotechnical stability of different characteristics to make analysis and comparison, andthe southern slope Chengmenshan outdoor copper sulfide ore weakest II-0profiles inheavy rain conditions under the stress-strain analysis to verify the predicted survey data,while revealing the law of interaction of rock and soil and water damage as well ascharacteristics of the issues raised similar projects need attention. Through the study ofliterature, books and other data, and numerical simulation analysis made the followingprogress:1）GEO software applications studied in two different forms of rainfall for twodifferent characteristics of soil slope seepage relationships change over time, the firsttype is different from the same rainfall time, the second type is different rainfallintensity rainfall same time. In the course of rainfall, soil decreases the range ofnegative pore water pressure, and the saturation line has been lifted. Distribution of thetwo soil pore water pressure has a direct relationship with the total rainfall, affectingdifferent rainfall intensity rainfall infiltration depth and uneven situation pore waterpressure equipotential lines. Rainfall in the short term will be a huge potential for porewater pressure linear tremendous impact.2）Different soil slope under the influence of different types of rainfall in the sameamount of rainfall，For sand and clay. short duration high intensity rainfall greaterimpact on the sandy slope stability， and stability of long duration low intensity rainfallearly clay slope greater. The total rainfall under the same circumstances， in the toe of the slope clay prone to saturation region， and the slope is the slope of sand shoulderprone to transient saturated zone.3）After detailed analysis carried out for the Jiangxi Chengmenshan openingCopper Sulfur southern slopes were extreme storm conditions, the weakest II-0sectional reasonable simplification, with the main stress field within the consolidated itsslope and displacement field analysis and comparison of the coupling and uncouplingcomparative safety factor in this condition, results of pore water pressure in thecoupling analysis resulting slope value to be greater than the slope of the resultingnon-coupled analysis of pore water pressure, resulting coupling analysis slope safetyfactor below uncoupled results were analyzed. At the same time, to prove the safety andreliability of the transport hub of Jiangxi Chengmenshan Copper Sulfur outdoorsouthern slope is also good, affluence is not high, so good drainage and a bare slopemaintenance.
