我国经济社会发展已步入“新常态”。作为地质调查和矿产勘查工作重要技术支撑的地质钻探行业,资金投入显著减少,地质钻探工作量大幅下滑,常规钻探施工产能过剩;另一方面,地质钻探新的服务领域不断扩大,包括深部科学钻探,地热能及非常规能源勘查,海洋、灾害防治、生态环境、地外天体、极地方面的钻探等。如何应对地勘行业出现的问题,是全行业共同面对的挑战。在对当前及今后一段时期地质钻探工程面临的困难、挑战和机遇等进行调研分析的基础上,对我国地质钻探未来的发展前景进行了预测,认为地质钻探工作量将进一步减少,新领域、新业态的钻探工程及先进钻探技术和装备需求将进一步加大,更加贴近国家需求,更加注重环保理念。  相似文献

介绍了国内外岩心钻机的发展现状,并结合目前我国的实际应用状况,分别就机械传动钻机、液压传动钻机与当今主流钻探工艺的适应性进行了分析比较,认为全液压岩心钻机是发展方向。但是,两种传动型式的钻机会在较长时期内共存,全液压岩心钻机的系列研发与机械传动岩心钻机的改型、改进应处于并重的地位。并指出在产品研发和产业化制造过程中需关注的问题。  相似文献

This paper first traces the major changes in the relationship between the (Orthodox) Church and State in the different Russian polities, using Madeley’s framework of historic mono-confessional blocs and multi-confessional belts. Second, it outlines the recent tendencies and characteristic features of church–state relations in today’s Russia. Third, using data from sociological surveys, it analyses the current dominant popular perceptions and societal attitudes towards religion and the State, including religious freedom. Being part of the historic mono-confessional Orthodox bloc, the different Russian polities produced different models of church–state relations: from a symphony of religious and political powers, through a forced nationalization of the Orthodox Church (Russian Empire from the époque of Peter the Great until revolution of 1917), and forced secularisation (during the Soviet Union), to a return of mutual support of (Orthodox) Church and State despite a formal (constitutional) separation in Putin’s Russia.  相似文献

The history of the development of the General Stratigraphic Scale (GSS), its significance, purpose, and difference from the International Stratigraphic Chart (ISC) are briefly reported. The most global achievements in the GSS refinement based on the Proceedings of the All-Russian conference at the Geological Institute of the Russian Academy of Sciences (May 2013) are considered. The main problems related to the GSS improvement are formulated: the structure of the Precambrian and Quaternary stratigraphic scales, the location of the Vendian System in the GSS, formal substantiation of the “Russian” stages of the Cambrian, Carboniferous, and Permian Systems, and the significance of the regional limitotypes of the ISC subdivisions.  相似文献

Seven main ore-forming systems—porphyry and epithermal; orogenic related to granitic intrusions; magmatic ultramafic; volcanic-hosted massive sulfide and volcanic–sedimentary; sedimentary basins; related to alkaline magmatic activity; and placers and weathering mantles—are sources of high-tech critical metals. The following promising types of ore deposits containing high-tech critical metals as by-products are recognized: Cu–Mo porphyry, Fe–Cu–Au and Pb–Zn skarn, base-metal epithermal, volcanic-hosted massive sulfide, base-metal stratiform, various tin deposits, and placers containing rare metals including REE. The mineral resources of critical metals in Russia are compared with those known in other countries. The contents of high-tech critical metals in ores of some noble-metal deposits of the Russian Northeast are reported. It is shown that the subsurface of Russia possesses considerable mineral resource potential for hightech critical metals, which allows new enterprises to be created or production of operating enterprises to increase.  相似文献
