中文摘要:
      伊犁盆地南缘侏罗系地层煤层层数较多,且在东西向、南北向各煤层厚度、层数、分叉情况的变化不一,将阿尔玛勒地区煤层赋存情况认识清楚,为后续开采提供扎实的地质依据。通过采用煤层自身特征法、标志层法、测井曲线组合法、层间距对比法综合对比分析,结果显示,该区含煤岩系形成于沉降速率均一,构造简单的沉积环境,各煤层无论在横向上还是纵向上连接都顺畅、自然、合理,为后期矿井设计提供了可靠的地质依据。
英文摘要:
      There are more coal layers in Jurassic strata in the southern margin of Yili Basin,and in the east-west, north-south coal seam thickness, the number of layers, bifurcation changes are different,In order to get a clear understanding of the occurrence of coal seam in almael area, comparative analysis of coal seam was carried out.This paper makes a comprehensive comparative analysis by using coal seam characteristic method, marker layer method, logging curve combination method and interval correlation method.The results showed that the coal-bearing rock system formed in this area due to the uniform settlement rate,a simple sedimentary environment,the connection of each coal seam is smooth, natural and reasonable in both transverse and longitudinal directions, which makes the comparison of the main workable coal seams in this area reliable, and provides a reliable geological basis for the later mine design.
