西曲矿生产布局和产品定位分析

通过对西曲矿主采煤层4号、8号、9号煤进行合理回采与衔接、产品定位的研究,得出结论:西曲矿产品定位为11级精焦煤,采取"三队四面"生产布局比较合适.这样,既缓解了4号、9号煤衔接紧张的局面,延长了4号煤服务年限,又合理有效地利用了井下资源,提高了精煤产率.

Highly Zn, Mn-rich calcite in calcareous tufa from the Qixiashan Pb-Zn Mine, Nanjing: a possible candidate for Zn-Mn removal from mining impacted waters

The exploitation of metallic mines may cause serious environmental problems. The removal of the heavy metals from the contaminated mining environments has become an urgent issue. In this paper, the occurrence and distribution of heavy metals in the calcareous tufa collected from the mining laneway of the Qixiashan Pb-Zn Mine in Nanjing were investigated by using multiple mineralogical techniques. Examination by X-ray diffraction spectrum (XRD) shows that calcite is the major component of the calcareous tufa. Several heavy metals such as Mn, Zn, Mg, Fe and Pb are detected in calcite by means of electron microprobe analysis. Although the heavy metal contents in the hostrock and the formation water are significantly low, the contents of Mn, Zn, Mg, Fe and Pb in the tufa calcite are as high as 23.65 wt%, 9.6 wt%, 0.76 wt%, 4.44 wt% and 0.66 wt%, respectively. The back-scattered electron image shows complex compositional zoning texture in the tufa, which is linked directly to variations in heavy metals, particularly in Mn and Zn. In addition, we also observed floccule and helical precipitations, which may be derived from the metabolism of the microbe. It is deduced that the occurrence and high concentration of heavy metals in tufa may be controlled by the activities of microbes. The results presented in this work suggest that calcite will be an important candidate for the remediation of the heavy metal contamination in mining areas.
