强烈动压影响下主体巷道联合支护修复的实践

Strongly influenced by dynamic pressure in the main roadway combined support repair practice

复杂矿区回采期间因动压影响而导致主体巷道失修的现象较为普遍,阻碍了煤矿安全高效发展。一般情况下,单一的维护方式满足不了支护要求,淮北矿区祁南矿通过"锚网索+喷浆+底板注浆"修复的实例,从支护的可行性研究入手,合理选择施工方案及支护参数,在实践应用中取得了显著效果。

The complex mining period of mining dynamic pressure caused by the main roadway disrepair phenomenon is relatively common, hindered the development of safe and efficient mine. In general, single maintenance mode can not satisfy the supporting requirement, that article through the Huaibei mining area in Qinan mine＂ cable anchor guniting grouting repair ＋ ＋ ＂ examples, from supporting the feasibility study proceed with, reasonable selec- tion of construction scheme and ＂supporting parameter, in the practice has achieved remarkable results.
