| 摘 要： | 为了确保大断面半煤岩锚网支护巷道的稳定性，提出在大断面半煤岩锚网支护巷道中，采用锚杆支护信息动态设计“五步”法，结合对实际支护效果的监测，对巷道的支护参数进行了优化。研究得出，该方法能保证巷道掘进期间的安全稳定，减少了顶板锚索的支护密度，缩短了顶板支护打锚索的时间，并极大地提高了巷道的掘进速度。

| Abstract: | In order to ensure the stability of the large cross-section roadway with semi-coal rock anchor-net supporting，this paper proposed the dynamic design of the "five-step" method using anchor supporting information in the large cross-section roadway with semi-coal rock anchor-net supporting.Combined with the monitoring of actual support effect，the supporting parameters of roadway were optimized.The research showed that this method can ensure the safety and stability during the tunneling，reduce the supporting density of the roof anchor cable，shorten the time for roof supporting to anchor the cable，and has greatly improved the tunneling speed. |
