Total of 23 bench samples were taken from the No. 7 Coal of Iqe Coalfield, Qinghai Province, China, following Chinese Standard Method GB/T 482-2008 （2008）. These samples were analyzed by powder X-ray diffraction （XRD）, inductively coupled plasma mass spectrometry （ICP- MS） and X-ray fluorescence （XRF）. The results indicate that the No. 7 Coal belongs to a low rank （*** =0.659%） and high-ash coal （40.54%）. Compared to common Chinese and world low-rank coals, the lqe coal contains anomalous concentrations of rare metal elements, rare-scattered （dispersed） elements and rare earth elements. The highest contents of Rb, Cs, Ga and REY reach to 180, 26, 37, and 397 ppm, respectively. Their average contents of these elements are 10.9, 15, 4.8 and 3.5 times higher than those of world coals, respectively. Minerals in the coal include kaolinite, quartz, muscovite, siderite, and traces of rutile, and brookite. Kaolinite could be main host minerals of Rb, Cs, Ga and REY. The anomalous rare element Rb and Cs accumulation in the Iqe coal is related to both organic and inorganic matter. The REY concentrations may be related to circulation of thermal solutions, contained or sorbed by clayey particles, and organic matter as well.

Continental organic-rich shales are well developed in the Dameigou Formation within the Yuka Depression of the Qaidam Basin. Here, the Rock-Eval pyrolysis, biomarkers, organic petrology, and stable carbon isotope have been carried out on the Middle Jurassic Dameigou Formation source rocks from the northwest part of Yuka Depression, Qaidam Basin in order to study their thermal maturity, source of organic matter(OM), and palaeoenvironment changes. The Rock-Eval pyrolysis data(e.g., T_(max)), vitrinite reflectance, and biomarker-derived thermal maturity parameters(e.g., carbon preference index, Ts/(Ts+Tm), C_(29)Ts/(C_(29)Ts+C_(29)αβ hopane), C_(30) αβ/(αβ+βα) hopanes, C_(29)ααα 20S/(20S+20R) steranes, and C_(29)αββ/(αββ+ααα) steranes) suggest all studied samples stay between immature and low mature stage. The maceral compositions, stable carbon isotope compositions, n-alkane distributions, and biomarker-derived source parameters(e. g., C_(27)/C_(29)ααα 20R sterane, ternary diagram of C_(27)-C28-C_(29)steranes, C24 tetracyclic terpane) indicate both aquatic organisms and higher plants are the source of OM in the shales, but land plants are dominant. Generally low gammacerane concentration and environment-related parameters(e. g., cross-plots of C_(27)/C_(29)ααα 20R sterane vs. Pr/Ph) indicate these source rocks may be derived from lacustrine and fluvial-deltaic environments with fresh water, which is also supported by the variations of stable carbon isotopes from OM in the source rocks. However, the stable carbon isotope compositions of OM in the source rocks were influenced by multiple factors(e.g., source types and depositional environment) in the Yuka Depression. Slightly brackish condition is recorded in the upper part of the ZK6-1 well favor the formation of lacustrine algae, as confirmed by high contents of C_(27) steranes and short-chain n-alkanes. The variation of reducing to oxidizing condition of study area is possibly associated with the periodical flooded r

Pollution of organic compounds and heavy metals in a coal gangue dump of the Gequan Coal Mine, China

引用

Chinese Journal Of Geochemistry 2013年第3期32卷 241-247页

作者： FAN Jingsen SUN Yuzhuang LI Xinyu zhao cunliang TIAN Duanxin SHAO Longyi WANG Jinxi Key Laboratory of Hebei Province for Resource Exploration Research Hebei University of Engineering China University of Mining and Technology (Beijing) The Fourth Construction Co. Ltd.of China Electronics System Engineering The Land and Resources Department of Wu'an

Samples around a coal gangue dump of the Gequan Coal Mine were collected in April 2009. GC (gas chromatography) and GC/MS (gas chromatography/mass spectrometry) were employed to analyze the composition of organic matter in the samples. ICP-MS (inductively coupled plasma mass spectrometry) was used to determine the concentrations of heavy metals. The contents of organic extracts are within the range of 140-750 mg/kg. Alkand aro-ratios are relatively high. Compared to those of the background sample (GQ13 ), the contents of saturated hydrocarbon compounds in all the samples are relatively high. The contents of polycyclic aromatic hydrocarbons (PAHs) are relatively high with the distance getting closer to the coal gangue dump. These indicate that organic matter in the samples is from coal particles of the coal gangue dump. The distributions of heavy metals are very similar: the contents decrease with distance from the dump, which indicates that the harmful heavy metals from the coal gangue dump have polluted as thick as at least 500 m.

以峰峰矿区辛安矿为例,经探查在+32 m、-100 m水平矿井涌水量中,周边小煤窑老空水约占总涌水量的70%。现已探明采空区内有3处重要涌水点均在大青灰岩含水层,最大涌水量可达6 m^(3)/min。由于涌水点位于封闭采空区,井下不具备定向钻探施工的条件。因此,拟采用地面多分支水平井定向钻探技术对大青灰岩含水层进行探查,通过综合运用超浅垂深定向施工、立体通道精细探查、定向水平孔投料、过水通道动水快速封堵等关键技术,不仅可以高效的识别出采空区涌水点,而且经现场抽水验证,地面多分支水平井注浆技术能够对井下突水点精准有效封堵。

Acta Geologica Sinica(English Edition) 2013年第4期87卷 1097-1108页

Total 138 coal samples and 14 parting samples were taken from the No. 6 Seam of the Jungar Coalfield, Inner Mongolia. These samples were analysed by optical microscopy, sequential chemical extraction procedure （SCEP）, inductively coupled plasma mass spectrometry （ICP-MS）, X-ray powder diffraction （XRD）, and scanning electron microscope in conjunction with an energy-dispersive X-ray spectrometer （SEM-EDX） analysis. The results indicate that the Li contents have reached the industrial grade of the coal associated Li deposit, and the total Li reserves have reached 2406600 tons, that is, 5157000 tons Li2O in the No. 6 seam in the Jungar Coalfield. The sequential chemical extraction procedure results suggest that the Li concentration is mainly related to inorganic matter. The minerals in the coals consist of kaolinite, boehmite, chlorite-group mineral, quartz, calcite, pyrite, siderite and amorphous clay material. Some Li could be absorbed by clay minerals in the Li-bearing coal seam. The chlorite phase？could be？most likely the host for a part of Li. The Yinshan Oldland should be the most possible source of Li of the coal.

以桑树坪矿11号煤8个样品为研究对象进行有机地球化学研究,利用气相色谱-质谱联用仪(GC-MS)、X射线荧光光谱分析(XRF)测试方法,结合工业分析、形态硫、随机镜质组反射率的测试结果,综合分析陕西韩城矿区桑树坪矿11号煤有机质的母质来源及成煤环境。结果表明,煤样全硫含量均值3.29%,油浸随机镜质组反射率均值为2.01%,为高硫贫煤。常量元素指相参数表明,煤样主要形成于还原沉积环境。饱和烃中的正构烷烃碳数分布存在前峰型及后峰型2种类型,前峰型主碳峰为C16,后峰型主碳峰为C_(26);结合ΣC_(22)−/ΣC_(23)+、(C_(21)+C_(22))/(C_(28)+C_(29))、Pr/nC17、Ph/nC18等分布特征指示煤样有机质母质来源于水生生物和高等植物的双重贡献。OEP值处于0.49~1.05,均值为0.84,指示桑树坪11号煤经历了不同程度的生物降解。饱和烃甾萜烷化合物分析中,w(Ts)/w(Tm)(Ts为18α(H)-22、29、30三降霍烷,Tm为17α(H)-27、29、30三降霍烷)处于0.83~1.21,w(Ts)/[w(Ts)+w(Tm)]在0.45~0.55,说明煤样热演化程度较高;芳烃化合物分析中,三甲基萘的甲基重排作用及甲基菲指数的分布特征均表示与煤样较高的热演化程度相关。芳烃化合物以萘系列、菲系列和联苯系列为主,且三芴系列(氧芴OF、硫芴SF、芴F)中含硫系列化合物明显高于含氧系列,同样指示了盐度较高偏还原条件的成煤环境。
