Abstract: The anchorage structure and force characteristics of small aperture resin anchorage cable in coal mine are analyzed. The anchorage force lower than its breaking force caused by the unreasonable anchorage structure about tension concentration type anchor cable is one of important reasons why it is difficult to control the deformation of rock surrounding in deep roadway, and this objective fact was pointed out. The anchor structure is comprehensive analyzed, one is anchor cable by tension concentration type for mining, another is anchor cable by tension dispersion type which commonly used in geotechnical engineering. The resin anchorage agent with slow condensation is developed which gel time 6 ~ 8h and pressure strength 60 MPa or more. On that basis ,the structure and construction technology of a new type of small aperture tensile dispersion anchor cable for mining are presented. Under the construction technology of anchor cable used for mining unchanged condition, time-division anchoring of resin coil with different anchorage sections in the same hole is realized. The anchor section shear stress of the anchor cable is dispersed to two places, and stress concentration in anchorage section is reduced. The application results of multi-pair mine engineering show that this technique can greatly improve anchor reliability and strength utilization of anchor cable. The matching performance of anchorage and breakage in anchor cables are improved, and the control effect of roadway deformation is enhanced significantly.
