贛州還認真執行國家下達的鎢精礦年度開采計劃，採取鎢精礦生產配額管理、公安部門批供火工產品、礦產資源管理部門辦理準運手續等措施，嚴格控制生產總量，做到了鎢精礦產量6年多來逐年穩中有降。Abstract : according to the variation in content of characteristic radioactive nuclide and the close relationship between high - grade associated elements in ore - forming components and gold, the ground gamma - ray spectrometry and x - ray fluorescence slectrometry can be used to reveal the existence of gold mineralization rapidly in field and make semi - quantitative evaluation of gold grade. this is of great significance in guiding field geological sample collection and mountain land engineering
文摘:通過測定特徵放射性核素的含量變化以及利用成礦組分中一些高品位共生元素與金密切的相關關系，可利用地面伽馬能譜與x熒光測量在現場快速揭示金礦化的存在，同時對金的品位進行準定量評價，以及指導野外地質采樣和山地工程。Considering this point and by applying trend surface fitting method and its principles of model optimization, the correspondingly numerical relations between the change of gas content and its spatial distribution in luling coal mine are obtained, based on this result, an accurate, reliable and quantitative forecast of gas in deep stopes and unexploited region can be achieved
結合趨勢面擬合及其模型優化的原理和方法分析得出了淮北礦業集團公司蘆嶺煤礦井田范圍內瓦斯含量的變化及分佈與其位置坐標的對應數值關系，依據該數值關系可對礦井深部采場和未開采區域實施比較準確、可靠的定量瓦斯預測。Based on the analysis of the evolution of the structural parameters of non - pillar sublevel caving of mines both in and outside china, it is pointed out that increasing continuously the sublevel height is not suitable for application in china because of the limitation of various factors while increasing the access space is the main way to reduce the amount of developing work, reduce the mining cost and increase the one - time caved ore amount so as to raise the mining strength and the labour production rate
分析了國內外礦山無底柱分段崩落法結構參數演變過程后指出，繼續增大分段高度由於諸多因素的限制，在我國並不適宜推廣應用，而增大進路間距卻是減少採準工程量、降低采礦成本、增大一次崩礦量、提高采礦強度和勞動生產率的主要途徑。分享友人
