  • Until recently, limestone yield production is mainly depend on geological investigation and boring. In the study seismic and electrical method are applied to calculate the basic data of limestone yield production. the result of geophysical prospecting, the depth of bed rock is approximately 17m. And there is a slightly difference between the limestone layer boundary which is drawn by electrical prospecting method and that of geological investigation.

  • This paper is designed to investigate the dynamic structure of optimal tariff imposed by the oil importing country from OPEC when OPEC increases the oil reserves through exploration and development. For this purpose, we used a Stckelberg differential game modeling approach, and tried to analyze two cases such that the one is the extraction cost is dependent on the oil reserves and the other is the extraction cost is independent of it. On the basis of this analysis, we propose that the importing contry has to impose dynamically inconsistent tariffs if the extraction cost is dependent on the oil reserves. Otherwise, she should impose dynamically consistent tariffs announced at initial time. In addition, we found that whether or not the exporting country uses some portion of oil produced for domestic consumption does not affect our policy proposition stated above.

  • 석재의 무분별한 개발로 인한 산림훼손을 최소화하고 상품성 있는 석재 가능성을 확인하기 위하여 채석허가 이전에 지질조사 및 시추탐사를 통한 매장량과 경제성 등 채석타당성을 평가하는 것이 필요하다. 골재가 부존하는 충적층은 다양한 입도와 지층 단면을 가지고 있기 때문에 이를 대상으로 골재를 채취하려면 골재의 품질과 매장량을 확인해야 한다. 또한 무분별한 골재 채취는 홍수시 유량과 유속을 변경시키므로 합리적인 채취량을 추산할 필요가 있다. (중략)

  • 과학자들은 오랜 연구끝에 원자의 분열시와 융합시에 막대한 에너지가 발생함을 알아내었고, 이의 효율적인 이용방법을 찾아내기에 성공하였다. 현재로서는 원자의 분열방법에 의한 원자력발전이 실용단계에 이르렀으며, 핵융합에 의한 에너지의 이용은 요원한 단계에 있다. 과학자들의 보고에 의하면 핵융합에 의한 에너지사용방법이 실현되면 그 재원은 무한정한 것이라 하면 현재사용하고 있는 원자력발전의 연료인 우라늄(매장량 약 2500톤)과 토륨(매장량 약 100만톤)만으로도 현재사용되고 있는 전화석재원(매장량약 3,500*$10^{9}$톤)의 20-30배에 상당하는 에너지를 얻을 수 있다고 보고 있다. 본 고에서는 원자력발전의 개발현황과 경제성을 검토하고 우리나라의 원자력발전소 건설계획과 추진현황에 관하여 살펴보기로 한다.

  • 지금까지 인류의 생활을 영위하기 위해 사용되어온 에너지 자원은 주로 화석연료가 대부분이었다. 대부분의 화석연료는 석유와 석탄으로 구성되어 있으며 그 중에서 석유는 인류의 생활에 없어서는 안될 매우 중요한 에너지 자원이 되었고 여러 방면에서 사용되고 있다. 그러나 대부분의 석유 매장량은 중동지방에 집중되어 있고 매장량이 한정되어 있다. 특히 석유는 국제 정세에 의해 중동지방으로부터의 원유공급이 불확실해질 수 있고 각 지역으로 석유공급을 할 때 관련되는 비용이 높은 문제점을 가지고 있다.(중략)

  • Given that China's resource research, exploration and development and resource economy policies are closely related to Korea's industrial competitiveness in the field of global mineral energy resources, it is important to establish the domestic and overseas resource development strategies. In 2020, China will revise and set standards for mineral resources to ensure efficiency in exploration and development and storage management. China's Ministry of Natural Resources has established the National Mineral Resources Plan (2021-2025), aiming to achieve national goals and strategies, and local governments at all levels are also establishing and implementing regional mineral resources plans. As a result, the supervision and management of geological mineral exploration activities have been strengthened, and the safety of industrial production management in the field of geological mineral exploration and development has been strengthened. China has developed guidelines for high-quality geological exploration, surveying and mapping, improved the level of geological mineral exploration and strengthened the mining supervision and management system. According to China's standardization of mineral resources such as solid mineral resources and petroleum gas mineral resources, a new standard system for resource management will be established in China to improve scientific understanding, rational management and utilization.

  • The Chinese government and its agencies were trying in order to solve the unstability of resource supply and demand. Ministry of Land and Resources of China(MLR) carried out a lot of national-level policy and planning for estimating the domestic mineral and energy resources potential and recoverable reserves, as the Chinese land and resources survey plan(1999~2010), the Chinese mineral resource survey and exploration plan(2008~2020), announcement for shale gas industry policies of China, the Chinese shale gas resources evaluation and selection project for its development priority areas(2012), and the plan for Chinese shale gas development(2011~2015). The two large sedimentary basins of Chinese shale gas reserves are Sichuan and Tarim basins with excellent potential, accounting for majority of the estimated national reserves. Recoverable gas-bearing shale of China was surveyed to be widespread. The volume of recoverable shale gas reservoirs in China has been estimated to be around 31 trillion cubic meters(1,115 trillion cubic feet). China is one of only three countries with the US and Canada to produce shale gas in commercial quantities. China is concentrating on technology development to enhance commercial production of shale gas, and on survey and exploration activities to increase its recoverable reserves. The trends related to shale gas development and R&D activities in China to respond to changes in international oil market should be actively monitored based on analysis of Chinese policies and technology.
