邯邢煤田岩浆侵入及对煤层煤质的影响

Magmatic Intrusion and Its Impact to Coal Seam and Coal Quality in Hanxing Coalfield

根据邯邢煤田岩浆侵入特点,分析岩浆侵入煤系层位与分布规律,岩浆侵入体的产状及岩性特征。邯邢煤田岩浆岩的侵入,不仅破坏了该区煤层的连续性和完整性,减少了煤炭的可采储量,并使煤层的物理性质、化学成分和工艺性能也发生了显著变化,致使煤质变差,煤炭工业价值降低。

According to magmatic intrusion characteristics in Hanxing coalfield, analyzed intruding horizon of coal measures and distribution pattern, intrusive occurrence and lithological characters. The magmatic intrusion in Hanxing coalfield not only destructed coal seam continuity and integrality, reduced mineable coal reserves in the area, but also obviously changed coal seam physical property, chemical composition and technical functions, made the coal quality poorer and lowered down coal＇s industrial value.
