针对火成岩侵入煤层、正常煤层进行了单轴、三轴和XRD实验，研究了不变质程度煤样的力学性质和细观成分特征。研究发现，受到火成岩侵入影响，煤体在宏观上表现出了石英的一些属性，煤体的变质程度加强，煤层发生了受热变质、硅化，脆性增强，容易破碎。
針對火成巖侵入煤層、正常煤層進行瞭單軸、三軸和XRD實驗，研究瞭不變質程度煤樣的力學性質和細觀成分特徵。研究髮現，受到火成巖侵入影響，煤體在宏觀上錶現齣瞭石英的一些屬性，煤體的變質程度加彊，煤層髮生瞭受熱變質、硅化，脆性增彊，容易破碎。

Uniaxial, triaxial and XRD experiment are did for volcanic intrusion coal seam and normal coal seam, coal sample's mechanical properties and mesoscopic composition characteristics with different metamorphic degree are studied. The study shows that coal shows some properties of quartz affected by volcanic intrusion, and coal metamorphic grade is strengthened, coal's heat damage and silicide are happened, coal is brittle and easily broken.
