| 摘 要： | 陕西省神府煤田新民区赋存的煤层为休罗纪低变质不粘煤和长焰煤。该区煤层由于变质程度低,有机组分含量高、氧含量高,加之区内煤层厚、埋藏浅,沟谷发育,造成煤层大面积自燃,而后形成的烧变岩分布广泛。不同类型的烧变岩在平面和剖面上都呈带状分布、煤层火烧区的分布范围主要受当时侵蚀基准面、煤层出露高度、出露范围以及煤层厚度的控制,并具有一定的规律性。

| Abstract: | The coal in Xinmin district of Shenfu coalfield, Shaanxi belongs to the low-metamorphic unsticky and long flame coal of Jurassic period. Owing to the low-metamorphic degree, high organic constituent, high oxygen, and the thick coal bed, shallow buried depth, numberous river valleys, the spontaneous combustion has occurred on a large area, and the formed barnt rocks are widely distributed. The different types of burnt rocks on the horizontal plane and section all presenta band distribution. The burnt range is mainly controlled by the erosional basis, cropping height and range and thickness of coal seams, and there are some regularities. |
