| 摘 要： | 通过对王坪井田煤层及地层分布特征、水文地质特征、断层特征及煤层渗透性等研究，结合对断层裂隙宽度、应力集中带、地层倾角等的计算，准确预测了断层及采空积水区防水煤柱的合理宽度，并指出矿界煤柱和隔水煤柱应按取大优先的原则，且这一原则对于石炭纪煤层的煤矿都适用。

| Abstract: | By the study of coal seam and stratigraphic distribution, characteristics of hydro-geology and faultage, coal permeability, combined with calculation of faultage-fraeture width, stress concentration zone, stratum obliquity, it accurately predicts faultage width and waterproof mine columniationpillar width in seeper area of bare area, and pointes out that priority of coal mining columns and waterproof mine columniationpillar,which adapts to Carboniferous coal seams. |
