蒙库铁矿床与镜铁山铁矿床的对比研究 - As it was difficult to extract the ore in the delta zone at ore body of jingtieshan iron mine , a rational extraction technology by ore cutting was applied so as to control the rock misplacement to ensure the extracted ore grade . as a result , good technical and economical benefits were achieved
阐述了镜铁山铁矿矿体下盘三角矿带矿量回收难点，采用合理的切岩回采技术，控制岩石混入量，保证出矿品位，达到较好的回收技术经济指标。 - 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
镜铁山矿是酒钢最主要的铁矿石生产基地，矿区山高沟深，地质构造复杂，自然地质环境较差，在长期人为开采活动的影响下，地质自然环境进一步恶化，山体裸露，岩层破碎，大量松散固体物质堆积在沟道及沟道两侧，泥石流灾害十分严重，严重制约了矿山的生产与发展。 1999年8月矿区黑沟南沟暴发生了严重的泥石流灾害，致使矿山停产10多天，造成5000多万元的经济损失。
