| This study discusses the formation of coal bearing basins and well types tectonicframework, and on this basis compares the coal geological division with the geologicalconditions of exploration and development; discusses the characteristics of coal resourcesspace, quantity, and distribution though the distribution map of coal resources and coal types;does quantitative analysis for the exploration degree of present coal resources on the bases ofthe construction of exploration and development formula, and combines coal resourcedistribution characteristics delineates the potential block; predicts the coal resources supplyand demand in future and analyses the comprehensive support capability through thehistorical analysis of the production and consumption of coal resources, at last points out thedevelopment trend of the coal resources prospecting and offers initial proposals. The mainoutcomes and understanding are as follows:(1)Coal basin experienced tectonic evolution in long time, formed mainland area tectonicframework just like a well, and established the basic framework of coal geological well fontpartition. The differentiation of the tectonic stress field’s nature is the fundamental factorswhich leaded to the differentiation of the major coal bearing basins in western and eastern,macroscopic structural deformation of coal measure and geological conditions of explorationand development.(2)Faulted coal basins to the east of Taihang mountain have some problems: thick Cenozoiccapping, fracture development, high ground temperature, high ground pressure, high waterpressure and so on; the coal series of depression type coal bearing basin in Midwest areshallow, within the basin, deformation is weak and geological conditions are simple, however,the water resource is lack and ecological environment is fragile; most mines’ explorationconditions are poor in terms of gas;(3)Coal resources is rich in west and north, poor in east and south, however, the watersources is rich in east and south, poor in west and north, at the same time the water inmountain area is more than it in plain. Coal resources, water resources, and economicdevelopment are significantly reverse distribution.(4)China has various kinds of coal, for example lignite, Low metamorphic bituminous coal,anthracite and so on, but they have seriously uneven distribution.(5)The quantitative analysis of exploration and development degree shows: the explorationlevel in shallow part is high in east and north, low in west and south; and development level in west is higher than it in east, and the distribution characteristic is not obvious.Eastern InnerMogolia zone, Shanxi, Shaanxi, Inner Mongolia, Ningxia zone, Yunnan, Guizhou, Sichuan,Chongqing zone, and northern Xinjiang zone, eastern Shenmu base, Eastern Inner Mongoliabase, northern Shanxi base, central Shanxi base, northern Shaanxi base, Xinjiang base,Yunnan and Guizhou base all have superior prospect of resource no matter in current or in thefuture.(6)In the future, the production and sales of coal resources will increase. In2020,2030and2050, the coal demand respectively are3.9billion,4billion and4.2billion, and Capacity cankeep pace with the demand growth; Increase in coal imports are more likely to focus on fillingthe gaps of some special industrial use or high-quality coal resources.Support ability of coalresources prospecting and exploitation is strong.(7)The Future exploration work in the eastern region should focus on Deep，Under largenappe and coal geological exploration in the periphery of old mines，while focus on coalseam gas and hydrological geological prospecting work，strengthen the ownership of unusedexploration coal resource, improve the exploration survey proportion, forming resourcecascade structure.(8)Exploration and development of coal resource in the macro and micro are expressed as a"strategic shift".The paper proposed the development layout strategy as:"protection andalleviate the eastern zone,Steady development in the central zone,To speed up thedevelopment of the West zone"... |
