滕县煤田七五井田岩浆岩分布特征及对煤层煤质的影响

Characteristics of Magmatic Rocks and Its Impact on Coal Quality in Qiwu Coalfield

摘要:

以七五井田为研究对象，通过对区内地质构造展布特征、岩浆岩分布特征进行分析研究，总结得出七五井田岩浆侵入规律，进一步弄清了岩浆侵入对煤层的破坏程度，并对岩浆岩对煤层煤质的影响程度进行了评价，为矿井生产过程中的开拓布置工作提供了依据。

Abstract:

In this paper, setting Qiwu coalfield as studying object, through analysis and study on regional distribution characteristics of tectonic structures and distribution characteristics of magmatic rocks, magma intrusion law of Qiqu coalfield has been summarized, damage degree of magma intrusion to strata has been clarified in further, and impact of magmatic rocks to coal quality has been evaluated. It will provide the basis for layout work for the mine developing in the production process.
