我国矿业权市场的培育与规制

我国已经基本形成以矿业权为核心、以矿业资本为动力、以咨询技术服务为纽带的矿业权市场体系,但市场中还存在政府干预矿业权市场,市场监管与调控不到位,市场主体缺乏自律与诚信等问题,严重制约矿业权市场的健康发展。现阶段,政府需要在完善矿业权市场建设过程中发挥主导作用,对矿业权市场进行全面监管并积极提供服务,优化调控手段,同时矿业权主体要加强自身的自律与诚信建设,建立矿业权市场信用体系,从制度上约束矿业权主体行为,共同培育市场环境,促进矿业权市场健康发展。

开滦煤矿唐山矿区与遂昌金矿矿山环境治理运作模式比较研究

本文在文献研究和实地调研的基础上,对比分析了开滦煤矿和遂昌金矿环境治理运作模式,分析发现开滦煤矿和遂昌金矿在矿山环境治理运作方式上的差异主要体现在治理主导者、治理主体、投资主体与融资模式、实施步骤和实施策略以及治理开发方式等方面。研究发现,矿区土地性质、参与主体利益诉求、环境问题性质及规模、矿区区位、矿山资源禀赋以及可资利用的条件等要素是造成两个矿山环境治理运作模式差异的主要原因。进一步分析发现,开滦煤矿环境治理运作模式,主要适应于毗邻城市、对城市生态环境影响巨大、以大面积采空区塌陷为主要地质环境问题的煤矿矿山废弃地的治理恢复;而遂昌金矿环境治理运作模式,主要适应于具有丰富矿山文化遗产资源和发掘价值、矿区在自然生态环境良好山区的金属类老矿山的治理恢复。     

新型羟肟酸捕收剂对硅孔雀石的浮选机理研究

随着易分选硫化铜矿日益消耗,氧化铜矿的开发显得尤为重要。针对硅孔雀石矿石采用直接浮选法存在捕收剂捕收能力不足的问题,研究中以苯甲酸甲酯和盐酸羟胺为原料合成了苯丙羟肟酸(BPHA),应用于硅孔雀石的浮选回收。微浮选试验表明,在pH值为9.0、BPHA用量为120 mg/L的浮选条件下,硅孔雀石的最大浮选回收率可达到75.2%。通过接触角、吸附量分析得出BPHA能提高硅孔雀石表面的接触角,增强其表面的疏水性。通过红外光谱(FT-IR)、X射线电子能谱(XPS)和扫描电子显微镜能谱仪(SEM-EDS)分析得出,BPHA与硅孔雀石作用后吸附在矿物表面,改变了矿物表面化学性质,并在矿物表面生成了疏水性的BPHA-铜物种,从而增加了硅孔雀石的可浮性。     

Use of Pb, <Superscript>18</Superscript>O,and <Superscript>2</Superscript>H Isotopes in Mining-related Environmental Studies

Abstract.   An isotopic and geochemical study of surface water and groundwater was undertaken at the Sullivan Mine, a sediment-hosted Pb-Zn massive sulphide deposit with a well-defined homogeneous Pb isotopic composition. The Pb isotopic composition of surface water and groundwater samples from near the mine site define a mixing line between Sullivan Pb and at least one other end member. The ¹⁸O and D isotopic results fall along an evaporation line that shows mixing between water from evaporative sources with water from meteoric sources.     

The influence of MoS<Subscript>2</Subscript> on tribology characteristic parameter of Ni60A/MoS<Subscript>2</Subscript> composite lubricating coating

The influence of MoS₂ on the tribology characteristic parameter of Ni60A/MoS₂ composite lubricating coating was researched on the UMT-2 fretting abrasion tester (USA). The result shows that with increasing content of MoS₂, the hardness curve of the composite coating decreases and the trend accelerates. Under the same experimental conditions, the mass loss of plasma spray composite coating without adding MoS₂ is 1.27×10⁻² mg. When the amount of MoS₂ reaches 35%, the mass loss is 0.96×10⁻² mg. It can be seen that adding MoS₂ phase can improve the wear resistance, the amplitude of which is close to 30%. The friction coefficient of plasma spray composite coating without adding MoS₂ is 0.23. Adding MoS₂ could decrease the friction coefficient of the coating and presents a downtrend. When the mass fraction is 35%, the friction coefficient is the smallest (0.13), and the range is doubled.

为了解决我国矿产资源日益突出的供需矛盾及重点资源后备储量严重不足的问题,我国在挖掘国内资源的同时,充分利用海外资源实施大型国有矿业资源型企业“走出去”战略,寻求和建立海外稳定的资源供应基地,成为维护我国经济安全,保障我国社会可持续发展目标的必然选择。为此,我国应成立政府专门部门协调和统筹大型国有矿业资源型企业国际化经营战略,制订大型国有矿业资源型企业走出去的国内扶植政策,开展围绕海外资源获取的资源外交;在税收、金融、社会咨询、军事保障等多个方面积极构建大型国有矿业资源型企业国际化经营的外部保障体系。     

Determining the amount of marketable blocks of dimensional stone <Emphasis Type="Italic">before</Emphasis> actual extraction

The lack of a proper decision variable impedes the planning of dimensional stone quarry operation. So far, “quasi-grade”, which may measure the stone quality, developed via multivariate statistical methods is offered as decision variable. However, the marketable blocks of dimensional stones should satisfy not only stone quality requirements, but also conform to certain dimensional standards, and these two are essentially incommensurable. Clearly, for stone with known quality, the amount of marketable dimensional stones (MDS) provides the best decision variable for planning (i.e. sequencing the operation of unit volumes). A method for determining the amount of MDS before actual extraction is presented. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 1, pp. 75–80, January–February, 2007.     

Electrochemical treatment of COD in biologically pretreated coking wastewater using Ti/RuO<Subscript>2</Subscript>-IrO<Subscript>2</Subscript> electrodes combined with modified coke

The electrochemical treatment of COD contained in biologically pretreated coking wastewater treated by a three-dimensional electrode system with modified coke as the particle electrode was investigated. And the electrochemical perfomance of the coke modified with various active components was studied. The results show that the coke modified with Fe(NO₃)₂ has the lowest energy consumption and higher COD removal rate under the same condition, and the modified coke has better surface characteristics for the purpose of this study. In addition, the kinetic constant was also calculated. The study shows that the three-dimensional electrode system with Fe (NO₃)₂-modified coke can give a satisfactory solution in biologically pretreated coking wastewater.
