【摘要】：煤炭資源屬于能源礦產(chǎn)資源之一,其應(yīng)用量占世界一次能源消費(fèi)量的25%。煤炭資源作為中國發(fā)展歷程所需的最可靠能源,它的基礎(chǔ)能源地位不可撼動,且我國以煤炭為主的能源格局將長時期存在。新疆有著豐富的煤炭資源,論文選取新疆東北部巴里坤三塘湖賦煤帶上的黑眼泉北井田為研究區(qū)。通過研究區(qū)域主要可采煤層(以下簡稱為“主要煤層”)的厚度、穩(wěn)定性、聚煤因素,運(yùn)用定性與定量相結(jié)合的方法,系統(tǒng)的總結(jié)了黑眼泉北井田主要煤層的賦存變化規(guī)律,分析了煤質(zhì)變化特征、煤的種類與煤炭的工業(yè)用途,根據(jù)主要煤層的煤質(zhì)特征及變化規(guī)律、煤質(zhì)指標(biāo)的相關(guān)性建立數(shù)學(xué)模型。通過研究分析得出以下結(jié)論:(1)研究區(qū)賦存著主要煤層4層,煤層賦存特征基本相似,其規(guī)律是由西南向東北向逐漸變深,對區(qū)內(nèi)煤層的連續(xù)性對比與穩(wěn)定性進(jìn)行了分析研究與評價,從主要煤層的走向和傾向變化規(guī)律上看,得出主要煤層在本區(qū)域含煤盆地南翼淺部,該盆地軸部(深部)在研究區(qū)的北部與東部。(2)研究區(qū)主要煤層的煤質(zhì)指標(biāo)中灰分(Ad)的分布變化規(guī)律大體上是特低-低灰煤由南向北由西南向東北逐級分布,全硫(St·d)含量的分布規(guī)律為煤層露頭向煤層深部由南向北逐漸遞增條帶試分布,發(fā)熱量(Qgr.d)總體呈現(xiàn)由煤層露頭向煤層深部數(shù)據(jù)逐漸遞減。(3)區(qū)內(nèi)主要煤層煤的發(fā)熱量與煤質(zhì)工業(yè)指標(biāo)的相關(guān)性,從整體上看煤的發(fā)熱量(Qgr.d)與水分(Mad)變化的相關(guān)性規(guī)律不明顯;主要煤層煤的發(fā)熱量(Qgr.d)與揮發(fā)分(Vdaf)有關(guān)系,并且與焦渣特征有關(guān)系,在本區(qū)內(nèi)焦渣特性基本穩(wěn)定,所以主要煤層較好的呈現(xiàn)了煤的發(fā)熱量越高煤的干燥無灰基揮發(fā)分越低的相關(guān)性規(guī)律;通過分析得出主要煤層煤的發(fā)熱量(Qgr.d)隨灰分(Ad)增大而降低。論文研究成果有助于本區(qū)域煤炭資源的綜合開發(fā)利用與遠(yuǎn)景規(guī)劃有著現(xiàn)實(shí)的意義,與此同時豐富了該含煤地層的相關(guān)理論基礎(chǔ)。
[Abstract]:Coal resources are one of the energy and mineral resources, accounting for 25% of the world's primary energy consumption. As the most reliable energy needed in the course of China's development, the basic energy status of coal resources can not be shaken, and the energy pattern dominated by coal will exist for a long time. Xinjiang is rich in coal resources. In this paper, the black eye spring north well field on the Santang Lake Fu coal belt in the northeast of Xinjiang is selected as the study area. By studying the thickness, stability and coal accumulation factors of the main recoverable coal seams in the area (hereinafter referred to as "main coal seams"), using the method of combining qualitative and quantitative methods, this paper systematically summarizes the occurrence and variation law of the main coal seams in the north coalfield of Heiyengquan, analyzes the variation characteristics of coal quality, the types of coal and the industrial use of coal, and establishes a mathematical model according to the coal quality characteristics and changing laws of the main coal seams and the correlation of coal quality indexes. Through the research and analysis, the following conclusions are drawn: (1) there are four main coal seams in the study area, and the occurrence characteristics of coal seams are basically similar, and their laws gradually become deeper from southwest to northeast. The continuity comparison and stability of coal seams in the area are analyzed and evaluated. From the trend and tendency of the main coal seams, it is concluded that the main coal seams are in the shallow part of the southern wing of the coal-bearing basin in this area. The axis (deep) of the basin is in the north and east of the study area. (2) the distribution and variation of ash (Ad) in the coal quality index of the main coal seams in the study area is generally the gradual distribution of ultra-low and low ash coal from south to north from southwest to northeast, and the distribution of total sulfur (St 路d) content is gradually increasing from south to north in the outcrop of coal seam. The calorific value (Qgr.d) decreases gradually from the outcrop of the coal seam to the deep data of the coal seam. (3) the correlation between the calorific value of the main coal seam coal and the industrial index of coal quality, and the correlation between the calorific value of coal (Qgr.d) and the change of water (Mad) is not obvious as a whole; The calorific value (Qgr.d) of the main coal seam coal is related to the volatile (Vdaf), and it is related to the characteristics of coke slag. The coke slag characteristics in this area are basically stable, so the higher the calorific value of coal, the lower the dry ash-free volatile content of the main coal seam. Through the analysis, it is concluded that the calorific value (Qgr.d) of the main coal seam coal decreases with the increase of ash (Ad). The research results of this paper are helpful to the comprehensive development, utilization and prospect planning of coal resources in this region, and enrich the relevant theoretical basis of the coal-bearing strata at the same time.
