Slope Stability Analysis And Control Study On The Area C Of Baiyun East Iron Mine

In pace with the expanding of human engineering activities and the rapid developmentof economy construction, the problem of predicting the stability of high and steep slope andthe occurrence of large disastrous landslide become the forward position in the research. it’sstabilization directly concerns economic benefit and safety production of mine enterprise.with the extension of open-pit mining and the slope angle, high steep slope safety controltechnology under complicated geological conditions will directly related to normal productor not.how to master the stability of open-pit high steep slope, and to ensure its security inmining process is still important research topic in the process of open-pit mining.This paper focuses on deformation mechanism and stability assessment comprehensiveanalysis of Baiyun open-pit high steep slope of rock. To carry on surveying and collecting agreat deal of related data on the spot to the mineral mountain, then the stability of slope ismade computational simulation by the model of the establishment. It followed the researchroute as field investigation--laboratory test--establishment of calculation model--stabilityanalysis of rock slope. In order to evaluate the stability of the slope, rock mechanics andparameters derived from laboratory test firstly were optimized by empirical formula.By analyzing the final draw:(1)Baotou Baiyun iron ore east mining area C major landslides is the presence of faults,especially the impact of the controlling fault F107.(2)by numerical calculation, the slope stability in the current state and continue to deepslope stability were simulated. The stability analysis showed that, in the case does not take adeep cutting or reinforcement measures, according to the original program continue to deepmining is extremely dangerous, most likely caused by the slope of the overall slump.(3)The1230platform to the1488platform, the first program on the basis of the originalmining design, cut slopes, and affected by faults with, increase the amount of mining. Thesecond program for the1348platform to the1488platform on the basis of the originaldesign cut slopes,1348following the original mining design.(4)By numerical simulation that the two programs can achieve the expected effect ofthe reinforcement. Comprehensive comparison of the safety factors, economic factors andthe amount of reinforcement works, the study suggests that the first reinforcement scheme ismore reasonable and economic.
