摘要
国内很多矿井尝试在井下使用TBM掘进开拓延深巷道,并取得了一定的实践经验.但在大坡度(≥±12°)、小转弯半径(R≤150m)的空间螺旋线路施工条件方面研究较少.海石湾煤矿三采区总体构造为一向南倾伏的簸箕形或箱状向斜,向斜在井田东部,由于受Fh-4的影响,局部可直立倒转,中部广大区域,煤层倾角较平缓,东西两翼倾角变陡.受采区面积及地质构造影响,通过研究TBM掘进机在大坡度、小转弯半径岩巷中的掘进技术,该项技术取得较好应用效果.
Abstract
Many mines in China have tried to use TBM to excavate deeper and deeper roadways underground,and have gained some practical experience.However,there are fewer studies on the construction conditions of space spiral line with large slope(≥±12°)and small turning radius(R≤150 m).The overall structure of the three mining areas of HaiShiWan Coal Mine is a southward-dipping skip-shaped or box-shaped inclination,the inclination in the eastern part of the well field,due to the influence of Fh-4,the local can be upright inverted,the central vast area,the inclination of the coal seam is relatively gentle,the east and west flanks inclination becomes steeper.Influenced by the mining area and geological structure,through the study of TBM tunneling technology in rocky tunnel with large slope and small turning radius,the technology has achieved better application effect.
