任楼井田二叠系含煤地层沉积相及成煤环境分析

Permian System Coal-bearing Strata Deposited Phase and Coal Formation Environment Analysis of Renlou Coal Field

本文通过对任楼井田含煤地层的特征及其变化形成过程进行分析,确定了该井田的成煤环境主要是在三角洲相沉积形成的过程中发育亚相、次亚相,为上煤组和中煤组提供了优越的成煤环境。

Based on the analysis of the characteristics of the coal - bearing strata and formation process of Renlou Coal Mine determined that the coal formation environment is mainly in the delta sediments forming process growing formation sub - phase and second sub - phase, and provided a superior coal for rning environment for main and middlle coal group.
