辽宁昌图亮中井田主要可采煤层对比

Comparison of the main workable seams in Liangzhong minefield of Liaoning province

本区含煤地层为白垩系下统阜新组,具有典型的陆相沉积特征,沉积旋回比较明显,其沉积特点,煤层层数多而且较薄,各煤层厚度、层间距变化小、结构单一、标志层发育,含有20层煤层。正是由于煤层多而个别煤层又有分叉现象,正确选择对比方法为煤田地质报告提交,煤炭资源/储量提供保障。本文介绍了在亮中井田煤层对比中采用的多手段对比方法。

In Liangzhong minefield , the coal bearing strata is Fuxin group of lower Cretaceous which has the characteristics of typical continental sedimentary , obvious depositional cycle , multiple and thin coal seams , stable thickness and spacing of coal seams , and development of marker layers .Because some seams have bifurcation phenomena , it is important to se-lect correct comparison method for providing rational coalfield geology report .In the paper , multiple comparison methods are used in coal seam comparison .
