Abstract

The physicochemical properties of Kuznetsk Basin coal are studied. The following distinctive features are confirmed for coal of moderate metamorphic development: minimum strength and gas-dynamic potential; and maximum risk of cracking and explosion, as well as maximum instability of the coal–methane system. For bed samples of different rank, we find that the petrographic characteristics of coal of metamorphic stages III–V include critical regions.

适度变质发育煤的性质

摘要

研究了库兹涅茨克盆地煤的理化性质。中等变质发育的煤具有以下特征：最小强度和气体动力潜力；最大的破裂和爆炸风险，以及最大的煤甲烷气系统不稳定性。对于不同等级的床层样本，我们发现变质阶段III–V的煤的岩石学特征包括关键区域。
