永城矿区地质灾害治理刻不容缓

永城是一个新兴的能源基地，是河南省最后开发的一个煤矿区。永城矿区虽然是一个新开发的矿区，但在开发伊始，其开采强度就非常大。随着矿区开发而引起的地质灾害和其它地质环境等问题日渐突出和明显，永城市工农业生产及人民生活等各个领域必将受到深远和广泛的影响。因此，认真研究永城矿山环境地质具有非常重要的意义。 一、矿山环境地质背景 永城市位于淮河冲积平原北部与黄河冲积平原的交汇部，地貌类型单一，区内地势平坦，仅在芒砀山等处就分布着10余个低矮山丘。永城在地层分区上属华北地台区鲁西分区徐州小区，由于新第三纪…     

新形势下山东矿山地质环境保护与管理工作探讨

山东矿产资源丰富,开采历史悠久,采矿活动引发的地质环境问题突出,恢复治理速度远远低于生态环境破坏的速度,严重影响了矿业的可持续发展,矿山地质环境保护与管理形势严峻。该文基于山东省矿山地质环境实际,分析了矿山地质环境保护与管理形势,探讨了新形势下山东矿山地质环境保护战略和管理机制,提出了多渠道、多元化解决治理资金,加强联合执法、督促和引导矿企主动履行矿山地质环境恢复治理义务,加强遥感监测与监控技术,激活保证金制度,发展绿色科技、建立完善的绿色矿山体系等建议,并指出随着煤炭集中开采区向鲁西南平原地带转移,推行清洁生产,发展循环经济性煤炭产业,建立多元化的煤炭资源可持续开发体系,是实现全省矿业领域绿色发展的关键。     

青海省民和县北山大理岩矿矿山地质环境影响分析及防治对策

民和县北山大理岩矿位于青海省东北部,青藏高原与黄土高原过渡带,地形总体上北西高南东低,山坡坡度30°～ 45°.本文在阐述矿山地质环境条件的基础上,依矿山开采方式,分析矿业活动对矿区地质环境的影响,并认为,矿业活动对地质环境的影响主要表现在:对土地资源的破坏和压占,对原生的地形地貌景观的破坏,引发或加剧不稳定边坡、泥石流等地质灾害.同时针对矿山地质环境问题提出了工程与生物相结合的综合防治对策.     

山东省矿山地质环境治理工作形势分析

山东是矿业大省,矿业在国民经济和社会发展中发挥着重要的基础作用。随着矿业经济的发展,矿产资源开发规模和强度不断增大,导致矿山地质灾害等一系列地质环境问题,严重地影响了矿业经济可持续发展,且危及社会稳定和人民生命财产安全。该文在剖析山东省地质环境问题及管理现状的基础上,总结了以往矿山地质环境恢复治理成效及项目安排情况,选取2个近年来实施的典型矿山地质环境治理项目对恢复治理效果情况进行了说明。对山东省地质环境管理发展趋势、地质环境问题发展控制能力进行了客观预测,提出相应的对策建议。     

枣庄市峄城区矿山开采现状与地质环境治理探讨

根据枣庄市峄城区矿山开采对地质环境造成的破坏及对矿业可持续发展调研分析,认为开采不仅对山体、植被等造成了直接破坏,还导致诸如地表塌陷、山体滑坡等安全隐患,矿山环境治理要从思想上、经费上、法律法规上、技术上入手解决,对已关停矿山地质环境治理,除加大宣传力度外,重点落实对矿山地质环境治理工作的责任、治理规划的编制实施,不断完善、探索治理方法和治理技术攻关及对策预案工作。     

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Foreword

正Rapid changes of Arctic sea ice cover have been in the focus of the international climate research community in recent years.Quite a few of nations have completed a large number of related surveys and research projects in the Arctic Ocean.Up to now,China has performed six research cruises to the Arctic Ocean resulting in a significant volume of research output.Improved knowledge on the atmospheree-sea ice-ocean interactions in the Arctic is a     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.     

Exposure ages and radiogenic ages of ureilite(GRV 024516) and ordinary chondrite(GRV 024517) from Antarctica

The GRV 024516 and GRV 024517 meteorite samples collected from Grove Montains,Antactica are ureilite and H5 ordinary chondrite,respectively.Based on the study of mineralogy-petrology,the cosmic-ray exposure ages and gas retention ages of these two meteorites were determinated and calculated.Their cosmic-ray exposure ages are 33.3 Ma,51.7 Ma,and gas retention ages are 1936.8 Ma and 3720 Ma,respectively.The ureilite contains diamond,graphite and amorphous C,which are mainly carrier of noble gases indicating obviously shock metamorphism effects,which induced 40Ar partial loss.The H5 chondrite indicates thermal metamorphism of parent body,its gas retention age fall the range between 3220 Ma and 4510 Ma of the least shocked H5 chondrites
