龙宫勘探区的岩浆活动 (岩浆热变质作用 )是影响二1煤性质和结构的重要成因因素之一 ,是造成本区二1煤煤种较多、分带明显的主要原因 ,对二1煤煤成气的形成和赋存也有较大的影响。对其进行分析研究 ,有利于煤炭资源的合理利用 ,有助于恢复地热演化史 ,对将来分析矿井瓦斯的成因亦是有益的。 The magmatic activity (magmatic thermal metamorphism) in the Longgong exploration area is one of the important genetic factors that affect the nature and structure of the second coal, which is the main reason for the large number of coal and the obvious zoning in the second coal. The formation and occurrence of coal-formed gas also have a greater impact. Analyzing and researching them is conducive to the rational utilization of coal resources, and helps to restore the geothermal evolution history. It is also beneficial to analyze the causes of mine gas in the future.
