新泰煤矿5号煤层赋存特征及厚度变化原因分析

The Occurrence Characteristics and the Cause Analysis of Thickness Change of 5 Coal Seam in Xintai Coal Mine

新泰煤矿5号煤层为矿井即将开采的主采煤层,是井田内厚度最大的可采煤层,但是厚度变化也较大。文章分析了新泰煤矿5号煤层的赋存特征及厚度变化规律,并从聚煤条件、河流冲刷及后期剥蚀等方面探讨了影响5号煤层厚度变化的原因,为5号煤层的开采规划,首采工作面的布置提供了思路。

The 5 coal seam in Xintai coal mine is the main coal seam to be mined.It is also the largest thickness of recoverable coal seam in the mine field,but the thickness change is also large.This paper analyzes the occurrence characteristics and thickness variation law of the 5 coal seam in Xintai coal mine,The causes of thickness variation of the 5 coal seam are discussed from the aspects of coal accumulation,river erosion and later denudation.It provides a train of thought for the mining planning of the 5 coal seam and the layout of the first mining face.
