摘　　要：焦作矿区位于河南省西北部、太行山南麓,地跨济源、焦作、新乡三市,矿区包括焦作、济源2个煤田。由于矿山的逐年开采,煤炭资源量显著减少,加之后期勘查投入的减少,导致目前对于矿区内煤炭资源现状的研究较为薄弱,现有的研究不足以支撑整个研究区的生产与开采。基于此,通过收集焦作矿区以往各类地质勘查资料、矿井采掘资料及矿井现场调查等,运用地质学、矿床学、构造地质学等,对研究区煤层煤岩特征、成煤环境、成煤规律等进行研究。研究表明,研究区石炭、二叠系含煤地层可分9个煤组,其中焦作煤田共含煤23层,煤层总厚16.04 m,其中主要可采煤层3层,可采煤层厚7.57 m。济源煤田共含煤22层,煤层总厚6.30 m,其中可采(局部可采)煤层6层,可采(局部可采)煤层厚4.61 m。其中,焦作煤田深成变质作用是煤变质的基础,区域岩浆热变质是区内煤变质程度增高的主要因素,在热变质作用的叠加作用下,煤的深成变质面貌已被改变。Jiaozuo mining area is located in the northwest of Henan Province,the southern foot of Taihang Mountain,spanning Jiyuan,Jiaozuo,and Xinxiang three cities,mining area includes Jiaozuo and Jiyuan two coalfields.Due to the year by year mining of the mine,the amount of coal resources has decreased significantly,coupled with the reduction of exploration investment in the later period,resulting in the current research on the status of coal resources in the mining area is relatively weak,and the existing research is not enough to support the production and mining of the whole research area.Based on this,by collecting all kinds of previous geological exploration data,mine mining data and mine site investigation in Jiaozuo mining area,using geology,ore deposit science and structural geology,etc,the characteristics of coal and rock,coal forming environment and coal forming law in the study area were studied.The research shows that the carboniferous and Permian coal-bearing strata in the study area can be divided into 9 coal groups,of which the Jiaozuo Coalfield contains 23 coal layers with a total thickness of 16.04 m,of which 3 main mineable coal seams with a thickness of 7.57 m.There are 22 coal layers in Jiyuan Coalfield,the total thickness of which is 6.30 m,of which 6 mineable(locally mineable)coal seams with a thickness of 4.61 m.The hypogenetic metamorphism is the basis of coal metamorphism in Jiaozuo Coalfield,and the regional magmatic thermal metamorphism is the main factor that increases the degree of coal metamorphism in Jiaozuo Coalfield,under the superposition of thermal metamorphism,the hypogenetic metamorphic appearance of coal has been changed.
