综放工作面过空巷超前支护方案设计

Design of advanced support scheme for goaf passing roadway in fully mechanized caving face

针对某矿9102综放面过空巷前的超前支护难题,运用现场实测、数值模拟等研究方法,探析了空巷围岩松动破坏状况,进而设计了空巷超前支护方案。实践表明,该支护方案实施后,空巷顶帮位移量、端面冒顶片帮程度等均得到了有效的控制,实现了安全高效生产。

Aiming at the difficult problem of advanced support in front of goaf in 9102 fully mechanized caving face of a mine,the loosening and failure of surrounding rock of goaf is analyzed by means of field measurement and numerical simulation,and the advanced support scheme of goaf is designed. Practice shows that after the implementation of the support scheme,the displacement of the roof and the degree of roof falling at the end of the goaf have been effectively controlled,and the safe and efficient production has been realized.
