研究区为一向斜北翼,区内沉积的晚二迭世煤系,东西走向长60余公里,宽2.5公里,面积约150平方公里。划分为九个井田和一个普查区。对区内主要煤层的2973层次煤样,作了分析研究。结果表明,各煤层煤质分属气、肥、焦、瘦、贫和无烟煤等六种牌号,各牌号煤的分布,不论沿走向或倾向,都有明显的规律性。本文试图在现有资料基础上,对区内煤的变质特征及共影响因素,加以探讨,不妥和错误处,望批评指正。
The study area has been inclined to the north wing, and the Late Permian coal measure deposited in the area has an east-west length of 60 km and a width of 2.5 km with an area of about 150 km 2. Divided into nine fields and a census area. The 2973 level coal samples of the main coal seams in the area were analyzed and studied. The results show that the coal quality belongs to six grades of gas, fat, coke, lean, lean and anthracite. The distribution of coal grades has obvious regularity no matter along the trend or tendency. Based on the existing data, this paper tries to discuss the metamorphic characteristics and influencing factors of coal in the area, and find out improper and wrong place and hope to criticize and correct it.
