露天采場分區實施不同采礦工藝的探索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。The theory of landscape ecology about drastic disturbance of landforms has been richened. a practical way could be found to identify the final direction of artificial ecosystem succession. moreover, the results can be applied into study the land reclamation and ecological rehabilitation of the developed opencast mines and developing ones in loess plateau
本研究結果的學科價值:豐富了極端生境下劇烈擾動地貌的景觀生態學理論，為確定人工正確誘導下的礦區生態演替方向提供了可借鑒的方法和途徑;應用價值主要體現:研究結果適宜於我國黃土高原正在開采和將要開採的大型露天煤礦的土地復墾與生態重建。Because the ore has been mined for long time, the nature geological environment has been getting worse and worse, such as the baldness of mountain body, the rock is weathered to pieces, a lot of loose material distributing along the gully and its banks, the disaster of debris flow is seriowsly, and the production of the mine is constrained by debris flow disaster ; for example, a debris flow broke out on august 1999 and resulted in catastrophic hazards to the jingtieshan iron mine, resulted in a huge economic losses of 50 million yuan
鏡鐵山礦是酒鋼最主要的鐵礦石生產基地，礦區山高溝深，地質構造復雜，自然地質環境較差，在長期人為開采活動的影響下，地質自然環境進一步惡化，山體裸露，巖層破碎，大量鬆散固體物質堆積在溝道及溝道兩側，泥石流災害十分嚴重，嚴重製約了礦山的生產與發展。 1999年8月礦區黑溝南溝暴發生了嚴重的泥石流災害，致使礦山停產10多天，造成5000多萬元的經濟損失。Based on the distribution of the mine - out areas, the author calculates the safety thickness of interval layers in the deposit
