【摘要】：木里煤田江倉礦區(qū)位于青海省天峻縣,與聚乎更礦區(qū)、弧山煤礦三者共同構(gòu)成了木里煤田中部含煤礦帶,是青海省重要煤炭礦產(chǎn)地之一。江倉礦區(qū)是木里煤田中最大的礦區(qū),礦區(qū)累計獲得煤炭資源／儲量20.83億噸,煤質(zhì)以焦煤為主。江倉礦區(qū)位于木里煤田中部,礦區(qū)呈北西西向展布,面積約55Km2,屬侏羅系中下統(tǒng)陸相碎屑巖含煤建造,礦區(qū)內(nèi)含煤地層厚度可達(dá)596.01m。共含煤20層(組),由上至下依次編號為1煤—20煤。本文在對江倉礦區(qū)的區(qū)域地質(zhì)、構(gòu)造以及礦區(qū)地質(zhì)特征綜合研究的基礎(chǔ)上,通過對礦區(qū)地層及地球物理特征的分析,建立了該區(qū)的煤層及其它巖層的定性、定厚解釋原則,并對江倉礦區(qū)主要煤層進(jìn)行了對比,總結(jié)了該區(qū)的主要可采煤層的地球物理特征,并做了煤層對比可靠性的評價。勘探實踐證明煤田地球物理測井能夠提供準(zhǔn)確、可靠的煤層、巖層以及構(gòu)造等方面的成果資料,彌補了鉆探施工過程中的缺陷,驗證了分層鑒定的成果；并利用煤巖層的地球物理特征,進(jìn)行了準(zhǔn)確的煤巖層對比,得到的煤層分布和厚度資料可信度較高。煤田地球物理測井在煤巖層對比方面具有獨特的優(yōu)勢,方法可靠、可操作性強(qiáng),從而提高了勘探效率和勘探工程質(zhì)量。
[Abstract]:Jiangcang mine area in Muli coalfield is located in Tianjun County of Qinghai Province. It is one of the important coal mining areas in Qinghai Province. Jiangcang mining area is the largest mining area in Muli coal field. The coal resources / reserves are 2.083 billion tons in the mining area. The coal quality is mainly coking coal. Jiangcang mine area is located in the middle of Muli coalfield, and the mining area is about 55 km ~ 2. It is a coal-bearing formation of Jurassic middle and lower continental clastic rocks, and the thickness of coal bearing strata in the mining area can reach 596.01 m. A total of 20 coal layers (groups), from top to bottom code for 1 coal-20 coal. Based on the comprehensive study of regional geology, structure and geological characteristics of Jiangchang mining area, through the analysis of strata and geophysical characteristics of mining area, the qualitative and definite thickness interpretation principles of coal seam and other strata in this area are established in this paper. The main coal seams in Jiangcang mining area are compared, the geophysical characteristics of the main mineable coal seams in this area are summarized, and the reliability evaluation of coal seam contrast is made. The exploration practice has proved that the coalfield geophysical logging can provide accurate and reliable data of coal seams, strata and structures, which make up for the defects in drilling construction and verify the achievements of stratification identification. Based on the geophysical characteristics of coal and rock strata, the accurate correlation of coal and rock strata is carried out, and the data of coal seam distribution and thickness are obtained with high reliability. Coalfield geophysical logging has a unique advantage in coal bed correlation, the method is reliable and operable, thus improving the exploration efficiency and exploration engineering quality.
