【摘要】：通過(guò)對(duì)南芬露天礦地質(zhì)邊坡各參數(shù)的調(diào)查與分析,運(yùn)用模糊數(shù)學(xué)綜合評(píng)判方法對(duì)采場(chǎng)邊坡進(jìn)行危險(xiǎn)性分區(qū),達(dá)到定性分析的效果,以對(duì)邊坡穩(wěn)定性進(jìn)行預(yù)測(cè)。運(yùn)用Arc GIS三維可視化分析軟件和赤平極射投影數(shù)據(jù)處理軟件,對(duì)邊坡地質(zhì)調(diào)查數(shù)據(jù)進(jìn)行室內(nèi)處理和分析。基于Arc GIS技術(shù)和邊坡危險(xiǎn)性分區(qū)結(jié)果,將災(zāi)害單元的離散變量差值計(jì)算為連續(xù)變量,實(shí)現(xiàn)南芬露天鐵礦采場(chǎng)邊坡危險(xiǎn)性3D可視化分區(qū)圖,最終得到最新的南芬露天鐵礦采場(chǎng)邊坡危險(xiǎn)性區(qū)劃圖。經(jīng)過(guò)本次對(duì)南芬露天鐵礦北山、下盤(pán)和上盤(pán)的系統(tǒng)調(diào)查,共發(fā)現(xiàn)顯著節(jié)理147條,顯著弱層和夾層98條,中等規(guī)模以上滑坡體22個(gè),危巖體56處,斑巖脈小構(gòu)造3條,沖溝41條。按照極危險(xiǎn)、危險(xiǎn)、次穩(wěn)定和穩(wěn)定級(jí)別,共劃分為4大區(qū),細(xì)化為35亞區(qū):其中,極危險(xiǎn)區(qū)細(xì)化為11個(gè)亞區(qū),占總面積的9.15%;危險(xiǎn)區(qū)細(xì)化為10個(gè)亞區(qū),占總面積的14.17%;次穩(wěn)定區(qū)劃分為9個(gè)亞區(qū),占總面積的20.01%;穩(wěn)定區(qū)劃分為5個(gè)亞區(qū)占總面積的56.67%。針對(duì)每一區(qū)域制作了相應(yīng)的邊坡治理方案。
[Abstract]:Through the investigation and analysis of various geological parameters of slope in Nanfen open-pit mine, zonation of stope slope using fuzzy comprehensive evaluation method to qualitative analysis results to predict slope stability. By using the software and stereographic projection analysis of 3D visualization of Arc data processing software GIS, indoor processing and Analysis on the slope of geological survey data. The Arc GIS technology and the slope hazard zoning based on the results of the discrete variable difference calculation unit disasters as continuous variables, implementation of Nanfen open pit mine stope slope hazard zoning map visualization 3D, finally get the latest Nanfen open pit mine stope slope hazard zoning map. After this time Nanfen open pit mine Beishan system investigation footwall and hanging wall, 147 joints were found significantly, significantly weak interlayer 98, more than 22 medium scale landslide, dangerous rock body 56 At the small structure porphyry veins 3, gully 41. According to the extremely dangerous, dangerous, stable and stable level, is divided into 4 regions, subdivided into 35 sub regions: the most dangerous areas are divided into 11 sub regions, accounting for 9.15% of the total area; the danger zone is divided into 10 sub area, accounting for 14.17% of the total area; stable region can be divided into 9 sub regions, accounting for 20.01% of the total area; stable region can be divided into 5 sub regions, the total area of 56.67%. for each zone made of slope treatment schemes accordingly.
