Abstract: According to the geological and production situation such as compound strata with large dip angle, high level in-situ stress, roadway crossing through different strata frequently and so on, the suitable supporting forms and scientific surroundings control methods of roadway in deep coal mine have been researched. The paper has taken typical roadway with depth of 1 300 m in deep coal mine as engineering background. Some main supporting design ideas of roadway in deep coal mine have been determined by systematic geo-mechanical on-site tests, analyzing the characteristics of surroundings deformation and its failure zones. The comprehensive control technology with combining bolts-net-cables and grouting reinforcement could prevent large and endless integral deformation of roadway surroundings. It is also important to take some extraordinary supporting manners in specific regions to avoid roadway’s local failures. At the same time, some supporting components and materials such as W-shape plate with 4 ribs, full anchored and pre-stress grouting cables, high-efficient antifriction gasket for bolts were designed to meet the needs of surroundings control. The engineering practice has proved that the comprehensive control technology that combines full-face strong anchor net supporting with grouting reinforcement could make roadway surroundings in stable state, reduce roadway repair tasks and achieve effectively supporting by once for roadway surroundings in deep coal mine by solving the supporting problems of surrounding rock deformation, long duration and serious destroy.

Key words: large-dip angle, compound strata roadway surroundings, roadway crossing through different strata, supporting and grouting reinforcement, comprehensive control technology
