Evaluation of logging of coal texture of seam 2 in southern Yanchuannan and analysis of its main controlling factors

Based on the original exploration and exploitation data, using the log and drilling core data, the authors have divided the coal texture into two types, i.e., hard coal and soft coal, and drew the distribution map. On this basis, we have analyzed the coal texture distribution characteristics and their geological controlling factors. The goal is to avoid strongly crushed coal reservoir and the area of bad fracturing effect for coal gas exploration
