摘要
介绍了锚梁网索联合支护技术在沿空掘进复合顶板煤巷中的试验情况,实践证明,该类巷道采用锚梁网索支护技术,既改善了巷道围岩的支护状况,保证了工作面的正常生产,又加快了工作面的推进速度,有效的提高了矿井安全高效的机械化程度。
Introduced the roof bolting with bar and wire mesh technolgy on the experimentaion circs of the complex roof gob - side entry, the practice proved that adopt the roof bolting with bar and wire mesh technolgy on that laneway, improved the support status of lane wall rock , enture working face produce in gear, as well as expedite the advance rate of working face, effective improve the mine mechanise pitch of the safety and high effect.
