The China National Administration of Coal Geology accomplished an assessment of coalbed methaneresources of China in 1988. The total amount of coalbed methane resources in China is 14336.944 billion m , occurring in recoverable coal seams and beneath weathering zones, with coalbed methane content equal to or higher than 4 m3 per ton and buried depths smaller than 2000 m, among which there are 967.51 billion m of predicted reserves and 13369.434 billion m of future reserves. The resources in coal reservoirs with methane content of more than 8 m per ton are 12444.087 billion m , and those with methane content between 4 to 8 m per ton are 1892.856 billion m . There are 35 districts in which the resources abundance is higher than 150 million m3 /km2 , 49 districts with the abundance between 50 million and 150 million m 3/km2 , and 31 districts with the abundance less than 50 million m3 /km2 . There is 9256.078 billion m3 of methane occurring in coal seams with buried depths less than 1500 m, and 5080.866 bi 相似文献

Graphite is one of the most essential non-metallic minerals with a wide variety of uses, and is an important commodity used in the emerging industry of China. Graphite is sourced from 170 mine areas in China from 25 provinces. This contribution is on a study of 15 regions in China with known graphite resources based on the spatial and temporal analyses of the regional metamorphic, contact metamorphic, and hydrothermal types of graphite. The knowledge gained on the metallogenesis of graphite in China is used to develop a model for choosing prospective regions for graphite, and to target areas for detailed exploration. It outlined 28 prediction areas with predicted graphite resources of about 1.63 billion tonnes to a maximum depth of 500 m in the Heilongjiang, Jilin, Liaoning, Shandong, Inner Mongolia and Hunan provinces. And of these, the predicted flake graphite resources in the Heilongjiang Province has been totalling almost a billion tonnes representing almost 60% of China’s graphite resource. As a result of this study, it is concluded that graphite has been formed during restricted periods of time, with the regional metamorphic type being the main style present in China. 相似文献

Gl obal recoverable resources of heavy oil and oil sands have been assessed by CNPC using a geology-based assessment method combined with the traditional volumetric method, spatial interpolation method, parametric-probability method etc. The most favourable areas for exploration have been selected in accordance with a comprehensive scoring system. The results show: (1) For geological resources, CNPC estimate 991.18 billion tonnes of heavy oil and 501.26 billion tonnes of oil sands globally, of which technically recoverable resources of heavy oil and oil sands comprise 126.74 billion tonnes and 64.13 billion tonnes respectively. More than 80% of the resources occur within Tertiary and Cretaceous reservoirs distributed across 69 heavy-oil basins and 32 oil-sands basins. 99% of recoverable resources of heavy oil and oil sands occur within foreland basins, passive continental-margin basins and cratonic basins. (2) Since residual hydrocarbon resources remain following large-scale hydrocarbon migration and destruction, heavy oil and oil sands are characterized most commonly by late hydrocarbon accumulation, the same basin types and source-reservoir conditions as for conventional hydrocarbon resources, shallow burial depth and stratabound reservoirs. (3) Three accumulation models are recognised, depending on basin type: degradation along slope; destruction by uplift; and migration along faults. (4) In addition to mature exploration regions such as Canada and Venezuela, the Volga-Ural Basin and the Pre-Caspian Basin are less well-explored and have good potential for oil-sand discoveries, and it is predicted that the Middle East will be an important region for heavy-oil development. 相似文献

The economic loss caused by the storm surgedisasters is much higher than that caused by anyother marine disaster in China, the loss from the severestorm surge disaster being the highest. Statistics showthat there were 62 typhoon landings over the east-southeastcoast of China since 1990, three of which,occurring in 1992, 1994 and 1997, respectively, caused themost severe damage. The direct economic lossesdue to these events are 9.3, 17.0 and 30 billion yuan(RMB, or about 1.7, 2.6 and 3.8 billion USD,respectively), which is much greater than the loss of 5.5billion yuan (RMB) on an average every year duringthe 1989–1991 period. This paper makes a comparativeanalysis of the damage caused by the three events andpresents an overview of progress of precautions againststorm surge disaster in China. The suggestedcounter measures to mitigate the loss from the severe stormsurge disasters in China is as follows: (1) Raisethe whole society awareness of precaution against severestorm surge disaster; (2) Work out a new plan forbuilding sea walls; (3) Improve and perfect the availablewarning and disaster relief command system; (4)Develop the insurance service in order to promptly mitigatethe loss caused by severe storm surge disaster event. 相似文献

As hydrogeological conditions of coal field in North China are complicated, coal mine water hazards have been occurring frequently.
Nearly 80% of coal mines are affected by Ordovician and Permo-Carboniferous Karst water. According to rough statistics, 200
incidents of water inrush have occurred since 1950, 1,500 persons have died, and there is an economic loss of 3 billion Yuan
(RMB). The climate of North China belongs to drought or semi-drought zone. So the recharge amount of ground water by infiltration
of precipitation is limited. Stronger coal mine water drainage has brought a series of environmental problems, such as water
resource and lots of famous Karst springs exhausted, surface collapse emerged, mine water contaminated. Coal mine water hazards
are so serious that the economic benefit of coal mines is dropping. Sustainable development of coal mines is affected. So,
preventing coal mine water hazards and protecting geological environment are essential. This thesis focuses on preventing
coal mine water hazards technologies. The technologies include four aspects: exploration of hydrogeological conditions; prediction
and forecast of water inrush; mining under safe water pressure; and sealing off groundwater by grouting. 相似文献

中国中西部前陆盆地的地质特征及油气聚集 总被引：92，自引：1，他引：92
油页岩是一种重要的替代能源资源,中国油页岩主要分布于中国15个省份(区),总查明资源储量329.89亿t,居世界第四位。其中,吉林省、广东省、辽宁省分别为174.27亿t、55.15亿t和45.05亿t,并分别占全国油页岩探明资源储量的52.83%、16.72%和13.65%。中国油页岩具有沉积时代以新生代为主,沉积环境以陆相为主的特征。中国高含油率的油页岩主要分布在新生代小型聚煤断陷盆地,而低含油率油页岩主要分布在晚白垩纪大型含油气坳陷盆地,且资源量巨大。中国小型断陷盆地油页岩,如桦甸油页岩的形成主要受构造、气候作用影响;而大型坳陷盆地,如松辽盆地油页岩的形成与全球缺氧事件有关,而缺氧事件常与海平面变化关系密切。新的评价体系把油页岩边界品位-含油率(ω)定为3.5%,并按不同品级、不同埋藏深度进行油页岩资源系统评价。坚持综合开发和利用,走炼油-化工-发电-多金属提取-建材一条龙联合生产是最佳开发利用途径。中国油页岩工业在中长期内将可实现油页岩工业化,具有广阔前景。 相似文献

鄂尔多斯盆地西南缘的彬长矿区开采侏罗系4号煤层,大地构造位置处于华北板块鄂尔多斯盆地渭北隆起带西部的彬长坳褶带内,矿区内瓦斯含量总体偏低,但褶皱地带及断层附近存在高瓦斯区域。研究结果显示,该区瓦斯含量主要受断层和褶曲构造的控制,瓦斯涌出量基本与煤层底板标高为负相关,与煤层厚度为正相关,与煤层埋藏深度和上覆基岩厚度呈正相关,总体上彬长矿区瓦斯涌出量从矿区周边向中部有明显增大的趋势,瓦斯绝对涌出量将随着煤矿生产能力的增大而增大。矿区瓦斯资源总量约44.91亿m3,可开发量约12.94亿m3,具有较好的开发前景,应尽早开展总体规划,统筹考虑,科学开发利用。 相似文献

煤矸石固废无害化处置与资源化综合利用现状与展望 总被引：1，自引：0，他引：1
煤炭生产和加工过程产生的大量煤矸石堆放地表,不仅造成土地压占、水土流失,而且还会引发山体滑坡、泥石流等地质灾害,给矿区生态环境造成严重影响。我国煤矸石累计堆存量已超过60亿t,压占土地1.3万hm2。2020年,我国煤矸石产量7.29亿t,综合利用量5.26亿t,综合利用率为72.2%。当前我国煤矸石综合利用具有存量和排放量大、产量高度集中、综合利用率不高,区域发展极不平衡,高附加值利用占比小等特点,现有煤矸石的无害化处置与资源化综合利用的规模和能力明显不能满足国家对生态环境保护及“双碳”目标下煤炭综合利用的相关要求。对此,提出煤矸石在采空区充填、地面筑基、塌陷坑回填与土地复垦等方面的规模化无害处置技术和方法,指出井下“采选充处”一体化固体充填开采和采空区地面膏体与浆体充填是控制煤矸石增量、规模化降低煤矸石堆存量的最有效方法。详细阐述煤矸石在发电、建材、资源回收、化工产品制备及农业等方面的综合资源化利用途径,提出构建“煤炭—固废发电—有价元素提取—化工产品—建材材料—井下充填—地面回填—农业应用”的闭合循环产业链模式,建立“多途径、多组分、多层次+梯级回收+生态修复+封存保护+井下高效自动化充填”规模化处置与综合利用体系的煤矸石未来产业化发展方向。 相似文献
