探测地雷技术研究综述

高敏感度、高可靠度、低花费传感器是全自动或半自动探雷机器人的首要和绝对的选择。当前,有许多技术能够被选来综合使用以满足上述的要求。金属探测器是一种传统的、成熟可靠的探测技术。但是,现在多种地雷含有少量的金属或者不包含任何金属,造成了用金属探测器探雷的困难。目前迫切需要研究发展新颖的探测技术以消除100万颗地雷对许多国家的影响。     

从电法勘探资料分析宋楼煤矿主斜井突水因素

根据宋楼煤矿主斜井直流电法勘探资料及矿井地质及水文地质条件的分析,煤矿主斜井突水原因应该是来自第四系砂砾石含水层及深层地下岩溶水。通过电法勘探确定裂隙发育带、富水区域、涌水部位,对此处实施钻孔注浆堵水后,恢复生产。     

煤矿水害多源信息预测方法研究

基于MAPGIS平台,用Visual C＋＋对其进行二次开发,研制了煤矿水害多源信息预测系统.通过对地震、电法、水文地质等多源数据进行处理后,在MAPGIS系统下进行成图、配准和空间定量分析,建立了预测模型.用该系统对煤矿实际资料进行了处理,结果表明其预测结果较传统方法更为准确.     

矿业开发与环境保护关系综述

笔者介绍了我国矿业发展经历的3个阶段，归纳出我国矿业开发带来的矿山环境问题主要有：地面塌陷、占压破坏土地、改变地质构造、破坏水资源、污染水、污染土壤、污染大气、瓦斯爆炸及河床抬高等。分析了环境恶化的原因主要与区域地质环境条件、历史、经济技术、矿山企业和地方保护主义等因素有关。最后提出了防治矿山环境恶化的对策，对难以治理的地区以预防、避让为主，历史问题由政府和企业共同解决，落实“谁开发、谁保护；谁受益、谁治理；谁破坏、谁恢复”的生态环境保护新机制，加强监管，加强防治对策研究，走综合勘探、综合评价、综合开发、综合利用的发展道路。     

永城煤矿区矿井经济环境价值综合评价

在初步估算永城煤矿区的环境成本的基础上，对该矿区某矿井经济环境综合价值进行了评价和分析。当考虑矿区煤炭环境成本时，煤炭资源开采的净现值变小，该矿井煤炭资源开采的经济环境综合价值变小。进一步计算了不同环境成本和贴现率时的净现值，为动态决策服务。     

淄博市洪山、寨里煤矿地下水串层污染形成原因及防治

淄博市洪山、寨里煤矿区隐伏的奥陶系灰岩裂隙岩溶水污染严重。水质污染突发于矿坑全面闭坑以后，污染范围与矿坑水区一致，地下水污染组份与矿坑水的高含量组份相同。水质恶化主要由矿坑水串层污染所致。在此针对串层污染形成原因及影响因素，提出了防治对策。     

云南矿业支柱产业建设的重点、难点及对策研究

云南矿业发展现状尤其是磷化工和有色金属等优势资源的调研和分析结果表明，矿业已成为云南工业的主体产业群体，影响云南矿业发展的难点主要是企业规模偏小，产品结构不合理，企业整体经济效益下降，国有企业困难面大，地质勘探投入少，矿山建设落后等，并据此讨论了矿业作为云南省支柱产业发展的思路和重点，提出相应的对策和建议。

Mechanisms of coal metamorphism: case studies from Paleozoic coalfields

Controls on coal metamorphism can be complex. In this paper, we examine four Paleozoic coalfields: the western Kentucky portion of the Illinois Basin, the Pennsylvania anthracite fields, the South Wales Coalfield, and the Bowen Basin. An increase in temperature with depth of burial is certainly a factor in coal metamorphism. In many coalfields, however, including the coalfields reviewed here, it has become apparent that such a simple mechanism does not explain the coal rank patterns observed. The flow of hydrothermal fluids through the coals has been proposed as a cause of coal metamorphism. Evidence includes inverted rank gradients, elevated CFL as an indicator of brine fluids, isotopic evidence for hydrothermal fluids, and vein and cleat mineral assemblages. In any case, multiple hypotheses must often be evaluated in the examination of any coalfield since the simple paradigm of coal rank increases with a simple increase in temperature with increasing depth does not fit the evidence observed in many cases.     

Experimental Study on Mine Spoils During Superficial Geochemistry Processes

Based on the mineral and chemical compositions of spoils taken from the Shilu Cu-Mo deposit and Hetai gold deposit, the leaching and batch experiments were made on spoils taken from these two deposits using the leaching column designed by the authors. The experimental results showed that it is not always true that the mine drainage is acidic. Its acidity depends on acid-buffering capacity of gangue, host rock and its alteration mineral assemblage. The composition of the drainage water is related with the interaction between superficial or underground water and solid materials in the spoils, including minerals, hydroxides and amorphous substances. The leaching extent of the element is related with its occurrence form in the deposit. The preferential flow results in leaching-out of heavy metals in large amounts. So it is important to prevent the generating of preferential flow in the system. The results will provide very important grounds for the comprehensive management of land and ecological rehabilitation of the mine site.
