四川盆地早古生代曾发生澄江、桐湾、云贵、冶里及加里东等5次地壳运动，其动力主要来自印度板块的向北俯冲和欧亚板块的向东漂移，并与青藏板块相碰撞，使青藏板块迅急向东，在盆地西部龙门山一带的薄弱地带发生断裂，致使青藏板块向东逆覆于扬子地台板块之上，相继四川盆地形成。5次地壳运动使龙门山大断裂带规模一次比一次大，使下古生界油气勘探储层也逐渐东移，勘探范围也逐渐变小。经勘探证实，共形成了雅安-龙女寺、泸州和天井山3个古隆起，是油气勘探的有利地区，特别是雅安-龙女寺古隆起区，不但规模大，各时期碳酸盐岩储层发育，局部构造多，且其西北翼遭受剥蚀的程度较深，经大气淡水长期淋溶，各储层必然会产生大量的古岩溶缝、洞，当其彼此纵横向相互交切后便可形成一个庞大的缝、洞网络空间，对油气聚集成藏十分有利。泸州古隆起和天井山古隆起上，也有较多局部构造可供钻探下古生界碳酸盐岩储层。

Early Paleozoic of Sichuan Basin underwent ifve crustal movements, that is, Chengjiang movement, Tongwan movement, Yungui movement, Yeli movement, and Caledonian movement, caused by the northward subduction of Indian Plate and the eastward drift of Eurasian Plate. The two Plates collided with Qinghai-Tibet Plate, causing the latter to swift to the east and collapse in weak zone of Longmen mountain area of western Sichuan Basin. As a result, Qinghai-Tibet Plate reversed eastward and covered Yangtze platform plate, and Sichuan Basin was formed in succession. Because of the ifve crustal movements, the big fault zones in Longmen Mountain got larger and larger in scale, as a result petroleum exploration reservoirs of Lower Paleozoic moved towards the east gradually and the exploration range got smaller. Exploration here proved that the Yaan-Longnvsi palaeohigh, the Luzhou palaeohigh, and the Tianjingshan palaeohigh were formed, which are favorable for petroleum exploration. In particular, t

结合三山岛金矿现行采矿方法应用情况对无底柱后退式竖向分条分段充填采矿法从方案的提出、理论依据及研究目的进行了说明,重点对采准工程布置方式,采场生产组织形式,采场施工技术等进行了介绍。通过与矿山现行盘区采矿法进行综合指标对比研究和总结,得出该方法具有以下优点:分段回采,大幅降低采准工程费用;中深孔落矿,降低凿岩爆破成本;倾斜分条回采,实现了定点出矿,既提高了出矿效率,又避免了充填体溃塌造成的二次贫化;竖向分条回采,能有效控制采场顶板及上盘冒落;后退回采,两翼回风,改善采场安全及通风条件等。加上天井施工以切代掘等多项创新技术的应用,解决了困扰矿山多年的中深孔采矿天井上掘问题。该方法设计合理,施工技术易于掌握,具有极高的推广应用价值。

Combined with the application situation of current mining method in Sanshandao gold deposit,this paper has carried a brief description on the scheme proposed,the theoretical basis and the research purpose for the method of backward vertical striping sublevel filling mining without sill pillar,and also has focused on the introduction of mining engineering arrangement,stope production organization form,stope construction technology and so on.By comparatively studied and summarized the mining method indicators in the existing panels in mine area,some advantages have been derived for this method,such as the sublevel stoping dramatically reducing the quasi project cost,the medium-length hole ore blast reducing the cost of drilling and blasting,the tilt striping stoping realized the fixed-point out of mine,which not only improved the efficiency of the out of mine, but also avoided the filling body collapse caused by secondary dilution.The vertical slitting stoping,effectively controlled the

对平稳工况下ZFYO型天井钻机主机减速器进行瞬态动力学分析,发现在正常工况下,齿轮轴与齿轮啮合过程中两轮承载不均匀。找出承受应力较大的齿轮,得到减速器在典型工况下的危险点的应力时间历程,结合材料的S-N曲线以及疲劳损伤累积准则,进行疲劳损伤分析,并采取相应的措施,减小天井钻机减速器磨损,提高天井钻机减速器的寿命。

The dynamic analysis on the main reducer of ZFYO raise drill in stable operation mode was conducted.It was found that the pinion and the gear carried different stress while they were meshing in normal operation mode.The gear was determined as the one carrying the larger stress,and variation course of the dangerous point of the reducer in typical operation mode was obtained.In addition,in combination with S-N curve of material and fatigue damage accumulation criterion,the paper analyzed the fatigue damage,and took corresponding measures so as to reduce the abrasion and prolong the lifespan of the reducer of the raise drill.

根据汨罗市1967—2013年雷暴日统计资料、雷电灾害统计及湖南省闪电定位系统资料，应用google mapper和google earth等软件对相关数据进行处理，并结合汨罗市人口密度特征，选取雷击密度、雷电流幅值、生命易损模数作为汨罗市雷电灾害风险生命易损性评估指标，建立雷电灾害风险生命易损度评估模型，采用4级分区法对上述雷电灾害风险生命易损性评估指标进行分级。将汨罗市29个乡镇按照3个雷电灾害生命易损性评估指标的所属等级获取相应等级值，作为雷电灾害生命易损性评估的评价指数。最后根据适当的权重对评价指数归一化处理，形成汨罗市雷电灾害风险生命易损度区划图。结果表明，高家坊镇、沙溪镇、白塘乡、范家园镇、磊石乡、八景乡为低易损区域，新市镇、白水镇、川山坪镇、黄柏镇、红花乡、李家塅镇、天井乡、智峰乡、古仑乡为极高易损区，长乐镇、大荆镇、城郊乡、黄市乡、新塘乡为高易损区，其余乡镇为中易损区。

Statistics of thunderstorm days, thunderstorm disaster statistics of Miluo City (1967—2013) and lightning strike positioning of Hunan Province were processed by using google mapper and google earth, moreover, population density of Miluo City, thunderstrike den-sity, lightning current value, life vulner-ability modulus were taken as the index-es for the life vulnerability evaluation of thunderstorm disaster in the city. Then thunderstorm disaster life vulnerability evaluation model was established, 4-grade zoning was adopted to grade life vulnerability indexes. Twenty-nine towns have their own scores according to the 3 grades of thunderstorm disaster life vul-nerability indexes, and the scores are taken as the evaluation indexes of thun-derstorm disaster life vulnerability. Final-ly, the evaluation indexes were normal-ized according to appropriate weights to form the thunderstorm disaster life vul-nerability zoning of Miluo City. The re-sults showed that Gaojiafang Town, Shax
