摘要

Based on systemic in-house and in-situ experiments on tensile strength of coal with brazil method and sleeve fracturing technique, this paper made an introduction of the basic theory, experiment equipment and experiment method for those tests, analyzed the distribution features of tensile strength values, and evaluated the tensile strength discrepancy and its cause; Thus laid a solid foundation for the application of tensile strength index in underground engineering.
