摘要
就难采煤层的涵义及其分类进行了较为全面的阐述 ,同时研究确定了各种类型难采煤层的定量化指标 ,依据这些定量化指标可以明确地区分煤层开采的难易程度 ,为煤层的进一步开发开采技术经济评价提供必要的基础数据 .
Based on comprehensive explaining definition and its classification of difficult mining coal seam, quantitative quote of all kinds of difficult mining coal seam are studied and defined. As a result, the defficulty easy extent of coal seam mining is distinguished definitively to supply necessary base data for economy appraisal to develop further mining technology of coal seam.
