摘要
系统地介绍了煤层抗拉强度的原位测试原理及数据处理方法，并对测试成果进行了详细分析，提出了煤层抗拉强度的取值方法，为煤矿防隔水煤柱合理留设提供了科学依据．
In this paper, the in-situ measurement and the related data treatment for tensile strength of coal seam are introduced and measuring results are analyzed, the methods of determining the tensile strength of coal seam are proposed, which provides a scientific basis for designing reasonable waterproof coal block.
