大河矿区下草坪矿段构造特征及其对煤层稳定性的影响

Tectonic characteristics of Xiacaoping Ore block of Dahe mine area and its influence on stability of coal seam

文章主要对矿区内的含煤地层特征、构造特征、构造对煤层影响等进行了认真地分析研究,认为本区的总体构造形态为向斜与背斜构成的复合构造,断层对煤层稳定性影响表现为中等,对煤层开采影响较大。这一研究为今后周边矿区地质勘探及煤炭开发提供了理论依据。

This paper mainly studies the characteristics of coal-bearing seam, structure and its influence on coal seam in the mining area.It points out that the overall structural feature of this region is composited by syncline and anticline,influence of faults on the stability of coal seam is moderate,and on the coal mining is large. This research provides a theoretical evidence for geological prospection and coal exploration of surrounding mining area in the future.
