摘要
为了精确计算煤炭资源储量和正确指导矿井采掘生产工作,需要总结及掌握地质构造对煤层的影响及其规律。根据永安东坑仔矿区已有的地质资料,并结合前人的研究成果,在分析矿区地质构造的基础上,揭示了构造对煤层结构、分布、厚度及煤层开采与储量等方面的影响。结果表明:矿区内褶皱可导致煤层发生塑性流变,影响煤层形态及厚度;密集发育的断层严重破坏煤层的连续性并形成无煤三角区;岩浆岩的顺层侵入导致煤层发生焦化或蚀变并出现分层现象。该研究对查明煤炭资源赋存特征及指导充分开采利用均具有一定的理论和实践意义。
In order to accurately calculate the coal resource reserves and correctly guide the coal mining production,it was needed to summarize and grasp the influence of geological structure on seam and its regularity.According to the existing geological data of Dongkengzai mining area,combined with previous research results,based on the analysis of the mine geological structure,the influences of structure on seam were revealed from texture,distribution,thickness and coal mining and reserve,etc.The results showed that the folds caused a plastic flow of coal seam in the mining area,influenced the seam form and thickness;intensive faults severely damaged the continuity of seam and caused triangle zone without coal;incursive magmatic rocks leaded to the coking or alteration of seams and made the seams separated.The research had certain theoretical and practical significance to find out the occurrence characteristics of coal resources and to guide the full exploitation and utilization.
