By infrared spectrum study, the limonite ( feooh nh2o ) can be considered the main colorating mineral in the yellow and red jadeite, and the hematite is another colorating mineral in the red jadeite. the difference of color tone is due to the n value in the molecular formula feooh nh2o and the content of crystal water and adsorbent water. the iron ion came from the effloresced and eroded rocks, and formed fe ( oh ) 3 colloid reacted with the surface water
周圍礦床的風化蝕變為表生水提供了鐵質，形成弱酸性的含fe （ oh ） _ 3膠體的水溶液，表生水流經翡翠礦石時， fe （ oh ） _ 3膠體附著在巖石的表面，經過脫水結晶和吸附，形成褐鐵礦膠體，褐鐵礦膠體沿裂隙或鬆散的礦物顆粒進入翡翠巖石中，逐漸累積沉澱，形成次生色層。In the various of mine exploitation sites, there are many loose debris and earth from strata
摘要各類礦山開發，都會大量擾動原始巖層，並且形成鬆散的廢棄巖土體。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。Abstract : the authors discuss roundly source of loose earth fo r impact - deposit debris flow to develop taking pingchuan debris flow, one of the quite typical impact - deposit debris flows in southwest sichuan province ， as an example in this paper. on the basis of detailed investigations in - situ, geotechn ial testing in lab and theory analysis, all results indicate obviously that moder ate and bulky loose earth in giant debris flow situating in southwest sichuan mo untainous area are main institute, whose tribulation are consistent with landform s. loose earth locating in mid - forepart catchment are quite unstable, so often be comes main source of loose earth of debris flow. formation of loose earth is cont rolled principally by geologic and geotechnical environment while human actions is the secondary factor for loose earth to form. in many times, human actions prov ide loose earth through loose earth stability
文摘:本文以極具典型的平川泥石流為例比較全面的分析了沖淤變動型泥石流的物源問題.根據現場調研及室內巖土分析進行的研究成果顯示，川西南高山深谷地區的大型泥石流溝中的鬆散土體以中、粗粒段為主，其分佈與地形密切相關；位於泥石流溝中、前部位的鬆散土體的穩定性最差，是補給泥石流的重要物源；鬆散土體的發育主要受控于地質及巖土環境，人類活動只能影響鬆散土體的穩定性The ground base of the newly added chute in 4 tailings reservoir at dexing copper mine is characterised by thick weathered layer, loose structure, fractured zone and landslip mass accumulation. as a result, the ground has a great subsidence and inefficient carrying capacity. in view of this, the grouting technology was adopted to reinforce the chute ground base. the on - site testing shows that the subsidence of the chute has been efficiently controlled and the carrying capacity of the ground base improved so that the stability requirement has been met
潘洛鐵礦主要使用的采礦方法是淺眼落礦的全面法和留礦全面法. 23礦體160m以上礦段上部為氧化礦和風化巖層，形成擠壓爆破和鬆散巖石覆蓋下的放礦條件.介紹了無底柱分段崩落法在該礦體開采中的應用.實際使用獲得的各項技術經濟指標還比較理想In order to optimize the parameters of running top coal under different coal and gangue fragmental size, on the basis of measuring and analyzing the distribution character of top - coal fragmental size, running top coal was studied for the coal seam with dead - unconsolidated thin sandstone roof by loose medium model experiment
摘要為了優化不同煤矸塊度條件下的放煤工藝參數，在實測分析頂煤破斷塊度分佈特點的基礎上，採用散體模型試驗的方法對煤層頂板為極鬆散細砂巖條件下的放煤工藝進行了研究。With the rapidly development of minefield and the rapidly increase of coal output, the excavation scope and depth will extremely rise, the excavation work is under the overlying by the thin rock strata, and under the thick loose bed, the population in mine field will be more and more, the relevant basic industries will also develop rapidly. the mines will discharge more water from the underground, and the production and living will also consume more water. so the original water resource balance system in the minefield will be broken, the ecological environment formed by the nature will be destroyed in some degree
隨著礦區迅速發展而煤炭產量的快速增長，既定在薄基巖厚鬆散層下的神東煤田開采范圍和深度勢必急劇增大，相應的人口也增加，與其相匹配的其它基礎工業一併迅猛發展，導致礦井外排水和生產生活用水直線猛增，這一系列生產和生活巨量用水必然會打破礦區原始的水資源平衡體系，不同程度的破壞自然形成的脆弱的生態環境。Destructive study of the cover rock relating to the fully mechanized mining with caving method under ravelly ground and nappe
