黑岱沟露天煤矿6号煤层风化煤分布特征及成因探讨

Distribution characteristics and causes analysis of the weathered six coalseam distributing in Heidaigou open-pit coal mine

从黑岱沟露天煤矿风化煤的煤质特征及分布规律着手,分析其形成原因,得出本矿风化煤形成的主要原因是断层及陷落柱,同时分析了风化煤与粘土岩在水平上互相替代的原因。

Based on the weathering coal properties and distribution regulation, the authors analyzed the reason the coal weathering, the major reasons the coal weathering of the coal mine are the faults and collapse of the under eoalseam karsts, and also analyzed the reason of the alternative bedding of the weathering eoalseam and the elaystone in the main time.
