煤层抗张强度原位测试研究

Measurement Study of Tensile Strength of Coal Seam

系统地介绍了煤层抗张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,提出了煤层抗张强度的取值方法,为煤矿防隔水煤柱合理留设提供了科学依据。

The in - situ measurement and the related data-treatment of tensile sterength 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.
