摘　　要：基于构造软煤与硬煤的物性差异,分析构造软煤分层在测井曲线上的响应特征;根据煤层段测井曲线的形态特征,将揭露区钻孔测井曲线初步判识的结果同钻孔邻近巷道煤壁观测的结果进行对比、验证,形成了一套测井曲线判识构造软煤技术。利用该技术获取了研究区的构造软煤资料,对研究区的煤与瓦斯突出危险性区域进行了预测。Based on the difference between hard coal and deformed soft coal on physical characteristics, analyzing the response that deformed soft coal seam is on well log. According to shape-characters of coal seam section on well log, this paper compared the initial results of identifying deformed soft coal using well log in uncovered district with those observed on coal face of tunnel adjacent to the drill hole, and then formed the technology that identifying deformed soft coal using well log. As well as the related information of deformed soft coal in study area was got by this technology; dangerous districts of coal and gas outburst were forecasted in study area.
