中文拼音 [lòutiānkuàngcǎikōngqū]
露天礦采空區
英文
bare ground-
The results show that distinct " bench " distribution rule takes on for the subsidence and distortion of bench - shape slope surface ; the movement range of bench - shape slope surface is smaller but its distortion is larger than those of flat surface and concentrated distortion occurs at every bench plan ; the surface horizontal distortion of bench - shape slope is still pressed in gob centre and tensioned in both sides of gob ; space - time effect should be taken into account for the stability of bench - shape slope influenced by underground mining
結果表明：露天煤礦臺階狀邊坡體的采動沉陷規律表現出很明顯的「臺階」分佈特點；臺階狀邊坡地表的移動范圍比平地地表要小，但變形卻更劇烈，且在各臺階平面處形成變形集中；臺階狀邊坡地表的水平變形仍然呈現出采空區中間受壓，兩端受拉的特點；臺階狀邊坡在地下開采擾動下的穩定性應考慮采空區的時空效應。Based on the distribution of the mine - out areas, the author calculates the safety thickness of interval layers in the deposit
在采礦過程中根據采空區分佈情況，確定露天開采時安全作業的隔離層厚度。Abstract : this paper gives the fe simulating analysis of the effect on road construction in the process of mine open - cut, analysis and evaluates stability of road foundation during many rock material steps excavation, concludes that the different conditions, for example, the rock caves, steps and the dis tance between the steps and road have influence on the road foundation stability
文摘:針對礦山在地下開采轉為露天開采過程中，原地采區域在露天采場臺階開挖過程中對露天采場公路建設及運營的影響，進行了數值模擬分析，並對通過各種巖體介質的露天采場公路路基在臺階開挖和汽車運營過程中的穩定性進行了分析評價，得出了在不同條件下，如空洞地區、臺階材料介質、材料界面、開挖臺階與公路距離等對路基穩定性影響的評價。
