安太堡露天煤矿复垦地土壤养分相关研究

以平塑安太堡露天煤矿为例，研究了矿区排土场矸石风化物和黄土二种主要母质发育的土壤有机质、全氮、速效磷、速效钾状况及其相关性。结果表明，矸石和黄土母质对有机质、全氮的影响显著，对速效磷、速效钾的影响未达到显著水平；黄土母质发育的土壤有机质和全氮含量呈显著正相关，而矸石风化物有机质和速效钾含量呈显著负相关，有机质和其它的养分指标相关性不显著。     

The Inversion Method in Measuring Noise Emitted by Machines in Opencast Mines of Rock Material

The inversion method was used to test vibroacoustic processes in large-size machines used in opencast mines of rock material. When this method is used, the tested machine is replaced with a set of substitute sources, whose acoustic parameters are determined on the basis of sound pressure levels and phase shift angles of acoustic signals, measured with an array of 24 microphones. This article presents test results of a combine unit comprising a crusher and a vibrating sieve, for which an acoustic model of 7 substitute sources was developed with the inversion method.     

露天煤矿生态系统脆弱性评价方法研究

露天煤矿的开采会对当地生态环境系统造成极大的损害，矿区可持续发展的目标要求在矿区开发过程中制定完善的生产建设、生态恢复重建规划来促进生态环境管理，这需要对生态环境系统进行科学的评价，并分析寻找影响可持续发展的原因，同时能够对各类措施的效果进行评价。本研究通过建立一个科学的、可操作性较强的生态环境系统脆弱性评价体系，为正确的制订矿区生态重建规划、生产建设规划以及生态环境保护规划提供基础理论保障和技术手段。     

Study on assessment of slope stability and mixed disposal of overburden in voids of Singrauli Coalfield

The mining industry can be considered the backbone of the Indian economy as well as facilitating the power that drives most of the other industries in the company. The overburden and waste rocks produced during coal mining are major concerns in regard to the amount of land that is required for their disposal, as well as the stability of dumps for these materials, which are of increasing height. Land reclamation issues are also a concern. In this work the adverse impacts caused by the dumping of overburden on land and acidic mine water on water bodies is discussed. Remote sensing tools were used along with the laboratory experimentation to assess the various impacts. This study also shows that silt released from waste dumps, can affected the angle of repose of the overburden dump slope. The angle of repose of the overburden materials varies with particle size composition. Thus, use of in‐pit crushers in large opencast mining operations can effectively reduce the area locked under the waste dumps. The acid neutralization potential of fly ash and overburden for the treatment of acid water was tested in the laboratory by using fly ash and waste rock materials on acidic coalfield water. The results are encouraging, and fly ash may prove to be a good acid neutralizer when used in conjunction of coal overburden material.     

Trace metal pollution in a Le'an River tributary affected by non-ferrous metal mining activities in Jiangxi Province,China

Sediment and water samples from the Jishui River were tested to determine the concentrations of As, Cd, Cu, Mn, Pb and Zn. The concentrations of Cu, Mn and Zn in the surface water close to the Fujiawu copper mine greatly exceeded the criteria maximum concentrations (CMC) of the Environmental Protection Agency. The concentration of Zn at a site near the small smelters also exceeded the CMC. Cd concentrations in surface water samples from 69% of the sampling sites were significantly higher than the CMC. Heavy Cd pollution of surface water resulted from the Shuanghua Smelter, the lead smelter, the lead–zinc mine and the small smelters downstream. The total metal concentrations in the majority of the sediment samples substantially exceeded the probable effect levels (PEL). Levels of As, Cd, Cu and Zn in surface sediment of the site close to the Shuanghua Smelter were 20 times higher than the PELs. The levels of Pb in sediment of the downstream sites near the small smelters and the lead–zinc mine were also elevated. Based on the results of the BCR sequential extract procedures and the risk assessment code, the levels of Cd, Cu, Mn and Zn in the sediment posed high risk.

区域水化学条件对淮南采煤沉陷区水域沉积物磷吸附特征的影响研究

在淮南潘谢采煤沉陷区水域的潘集(PJ)、顾桥(GQ)、谢桥(XQ)各选一研究站点,研究区域水化学条件下溶液离子组分对表层沉积物磷(P)吸附特征的影响.等温吸附实验分别在纯水、NaCl、CaCl2、NaHCO3和NaHCO3+CaCl2共5组环境溶液中进行,其中前4组设置为探讨各组分对P吸附的单独作用,最后1组代表各组分的综合作用.结果表明,环境溶液设置对P的吸附特征有重要影响,Ca2+能显著增强沉积物对P的吸附潜能,而弱碱性环境(NaHCO3组)则不利于沉积物对P的吸附,实际水化学条件下的作用则表现为二者的综合,但Ca2+增强作用要显著大于碳酸盐弱碱性缓冲体系的弱化作用.3个站点沉积物P的零吸附平衡浓度(EPC0)的均值分别为0.059、0.032和0.040 mg·L-1,总体上有向水体释磷的趋势,PJ站点释放潜能要高于GQ和XQ站点,与研究水域营养水平密切相关.由于特殊的沉积环境,研究水域P释放潜能比富营养化程度较高的湖泊要弱,接近于营养水平较低的水体.
