霍州辛置桃沟矿泉水的形成条件及水质特征

桃沟矿泉水暴露于辛置煤矿的通风斜井中，为低矿化度、低钠、锶重碳酸钙镁型饮用天然矿泉水，在开发利用过程中应十分重视环境保护及卫生检测。     

湖南瑶岗仙钨矿中石英的标型特征

以湖南宜章县瑶岗钨矿床为例，较系统地研究了石英的标型特征，如稀土元素，微量元素，铝及碱质含量，热发光性，包体化学成分和温度，红外光谱等，总结了这类矿床的石英标型特征以及含矿石英与无矿石英的区别。     

Coal resources,production, and quality in the Eastern kentucky coal field: Perspectives on the future of steam coal production

The Eastern Kentucky coal field, along with adjacent portions of Virginia and southern West Virginia, is part of the greatest production concentration of high-heating-value, low-sulfur coal in the United States, accounting for over 27% of the 1993 U.S. production of coal of all ranks. Eastern Kentucky's production is spread among many coal beds but is particularly concentrated in a limited number of highquality coals, notably the Pond Creek coal bed and its correlatives, and the Fire Clay coal bed and its correlatives. Both coals are relatively low ash and low sulfur through the areas of the heaviest concentration of mining activity. We discuss production trends, resources, and the quality of in-place and clean coal for those and other major coals in the region.     

胶东乳山金矿双山子矿区黄铁矿环带结构研究

胶东乳山金矿双山子矿区黄铁绢英岩中的粗粒黄铁矿发育规则环带结构。本文通过黄铁矿单晶发育过程中形态、热电性和化学成分特征的研究，阐明了黄铁矿多阶段生长的历史；揭示了成矿溶液中S、Fe过饱和度和黄铁矿形成温度变化的韵律性或多旋回性；探讨了黄铁矿中微量组分与其导电类型之间、黄铁矿形态与其热电性和含金性之间的有机联系；进一步肯定了黄铁矿{21I}、{211}习性晶、P导型、As、Sb、Se、Te杂质的金矿示矿功能。     

辽宁西部TM图像逆冲断层解译及找煤研究

辽西坳陷中的断陷盆地边缘逆冲断层发育。本文描述了逆冲断层的TM影像特征,解译划分了逆冲断裂带,并指出逆冲断层对找煤远景解译推断的意义。具体分析了南票、北票矿区外围的找煤远景,还应用影像特征探索性地对逆冲断层倾角进行了解译分类。     

Reliability level III method in design of square pillar resting on weak floor stratum

Summary Current methods of design of pillars resting on weak floor strata involve only a deterministic, conventional safety factor calculation, based on material parameters treated as the mean values taken from observations. In a case where high parameters variability occurs, these methods may lead to fatal design errors resulting in excessive pillar settlement and roof falls. Therefore, to include the influence of parameters quality, the new approach based on reliability level III method was developed. Consideration was given to the identification of the system parameters importance, and to density function for the safety factor treated as a random variable. Design procedure involving floor probability of failure was illustrated by numerical examples.     

郴州地区煤田地质特征及找煤远景区

本区地槽型煤田,主要是下寒武统牛蹄塘组,由一套浅海相碳质板岩为主组成的含钒石煤岩系,与下伏地层呈整合关系。地台型煤田有下石炭统测水煤系和上二叠统斗岭煤系,它们是以一套海陆交互相的细碎屑岩为主,夹菱铁矿或黄铁矿结核及煤组成,与下伏地层呈整合关系。其中斗岭煤系的煤层分布广,煤层及煤质较好,是本区找煤的对象。地洼型煤田,为上三叠—下侏罗统煤系,呈零星小块分布,是一套以陆相,杂色粗碎屑岩为主,夹泥岩及煤组成,与下伏地层呈不整合关系。主要发育在资兴市和宜章县一带,找煤条件次于斗岭煤系。     

利用水化学场,温度场判断矿坑水补给源及其比例

不同补给源的水,其水质、水温存在差异。根据质量和热量守恒原理,通过对不同补给水源进行长期观察,可确定矿坑水的补给源及其比例。作者推导出了存在二种和三种补给水源情况下各补给水源所占比例的计算公式,并应用到湖南洞口县的石下江煤矿,取得了良好效果。     

诱发地震中的非双力偶震源

在诱发地震的研究中，用小孔径地震台网在近场观测，其震源机制的Ｐ波初动除Ⅲ象限分布的双力偶外，还有不是Ⅲ象限分布的非双力偶震源机制。双力偶震源机制是剪切破裂机制。非双力偶震源机制为向内源炸型和张破裂机制，以及在适当方向上两个以上双力偶迭加的结果。
