  • 12501.全球煤层气煤层市场报告(2014-2018年)

    [采矿业] [2014-01-14]

    The Global CBM market is expected to witness moderate growth during the period 2013-2018. This is mainly due to the slow shift to alternative forms of natural gas. The market was dominated by the Americas in 2013, followed by the APAC and the EMEA regions. The overall market is expected to grow at a CAGR of 3.5 percent during the forecast period.

  • 12502.全球铝市场报告(2014-2018年)

    [采矿业,有色金属冶炼和压延加工业] [2014-01-14]

    The Global Aluminum market is expected to grow at a CAGR of 5.89 percent during the period 2013-2018. China led the Global Aluminum market, both in terms of production and consumption, followed by the EMEA region and the Americas. The growth of the Chinese economy and the increased use of aluminum in the Automotive, Construction, and Packaging industries are expected to increase the growth of the global market during the forecast period. The other leading consumers of aluminum include Russia, Canada, the US, Australia, and the UAE. The economic growth of the emerging markets is expected to drive the demand for aluminum, and will be the major driver of the global market during the forecast period.

  • 12504.2014年煤炭行业发展报告——展望篇

    [电力、热力、燃气及水生产和供应业,采矿业] [2013-12-31]

    2013年底至2014年,经济基本面对煤炭需求的拉动力度弱势趋稳,但煤炭需求总体偏弱的格局难以改观;煤炭增产动能较强,煤炭运能可调空间加大,煤炭进口高位波动,受煤价较低、安全防治、库存制约以及环保压力等因素影响,煤炭有效供给的将在相对低位波动。预计2014 年煤炭供求将呈总体宽松、阶段性过剩态势,如果气候因素所带动煤炭需求明显好于正常水平,则供求关系会阶段性地朝供求平衡方向回调。

  • 12506.位置治疗有关睡眠障碍技术的管理

    [采矿业] [2013-12-25]

    Positional patients are defined as obstructive sleep apnea(OSA) patients in whom respiratory disturbance index(RDI) or apnea-hypopnea index(AHI) is at least twice as high in the supine position than in the non-supine position.Positional therapy (the avoidance of the supine posture during sleep is a simple behavioral therapy for mild and moderate sleep disordered breathing.

  • 12507.全球提高石油采收率(EOR)市场报告(2014-2018年)

    [石油加工、炼焦和核燃料加工业,采矿业] [2013-12-22]

    EOR is a technique to increase the production of oil fields other than those that are conventionally used for the oil extraction process. EOR is the third phase that is used for oil recovery after the failure of primary and secondary oil recovery methods. Primary oil recovery is the first stage in the production of hydrocarbons by using natural energy available in the reservoirs such as gas drive, water drive, and gravity drainage. When the natural energy from the reservoirs is depleted, then oil is recovered by secondary recovery methods using an external source such as injection of either natural gas or water. The primary and secondary methods can recover up to 30-40 percent of the hydrocarbons available in the reservoirs.

  • 12508.南海油气资源开发研究——基于石油安全的视角

    [采矿业] [2013-12-18]

    石油安全最早是一个军事领域的概念,主要是指以石油为战争机器的燃料供应安全问题[1]。20世纪70年代,世界第一次石油危机使得石油安全作为一个与石油危机相对应的概念而被广泛使用。从经济安全范畴看,石油安全的基本定义是“一种以不中断经济进程的方式和价格水平满足需求的流动[2]”。其核心内容是石油的安全供给和油价的合理波动。从供应安全的角度看,石油安全是指“一个国家或地区所能获得的石油资源持久、稳定、足量地满足国民经济可持续发展需要的状态”[3]。也就是说石油的数量、质量以及地区均衡性都会影响到一个国家或地区的石油安全。

  • 12509.水平注水采油

    [采矿业,电力、热力、燃气及水生产和供应业] [2013-12-17]

    Solar energy has become a major alternative for supplying a substantial fraction of the nation's future energy needs. The U.S. Department of Energy (DOE) supports activities ranging from the demonstration of existing technology to research on future possibilities. At Lawrence Berkeley Laboratory (LBL), projects are in progress that span a wide range of activities, with the emphasis on research to extend the scientific basis for solar energy applications, and on preliminary development of new approaches to solar energy conversion.

  • 12510.水体下近距离煤层组安全煤(岩)柱的留设研究

    [采矿业] [2013-12-15]

    为合理开发煤炭资源,最大限度地提高水体下煤炭资源的利用率,解放呆滞的煤炭资源,文章以姚桥煤矿近距离煤层组7、8号煤工作面为例,运用地质勘探、实验室土工试验和理论分析等研究方法,分析获得第四系松散层下部含、隔水层性质,从而确定了安全煤(岩)柱留设类型为防砂安全煤(岩)柱,进而合理确定了7、8号煤层安全煤(岩)柱合理留设尺寸及7、8号煤层的开采上限.
