The increasing demand for cleaner source of energy forces India to explore various energy sources, and in this process, coal bed methane gas attracts lot of attention for its favourable characteristics including abundance of coal, clean gas, mitigation of greenhouse gases, reduction in hazard in mines, etc. However, the challenge faced during exploration and production varies from depth of seam, heterogeneity in coal characteristics, rank, sorption capacity, saturation, etc. So the detail analysis of various properties is important for economical extraction of gas. The present paper investigates coal properties and their influence on coal bed methane potentiality. Samples from core wells have been analysed in laboratory using proximate and ultimate analyser. Linear correlations between coal constituents and vitrinite reflectance as well as sorption capacity of coal have been established statistically. Mutual relations among proximate parameters are developed.

印度东北部Tikak Parbat地层煤特征的实验室研究，用于煤层气研究

对清洁能源的需求不断增长，迫使印度探索各种能源，在此过程中，煤层气因其良好的特性（包括丰富的煤炭，清洁的气体，减少的温室气体，减少了甲烷的危害）而受到了广泛的关注。然而，在勘探和生产过程中面临的挑战因煤层深度，煤质特征的不均一性，等级，吸附能力，饱和度等而异。因此，对各种性质进行详细分析对于经济地开采瓦斯十分重要。本文研究了煤的性质及其对煤层气潜力的影响。来自核心井的样品已在实验室中使用最接近和最终的分析仪进行了分析。统计学上已经建立了煤成分与镜质体反射率以及煤的吸附能力之间的线性相关性。建立了附近参数之间的相互关系。
