摘 要:为验证预应力全长锚固锚杆(索)等支护技术在冲击地压矿井沿空掘进巷道的应用效果,在赵楼煤矿5304工作面轨道顺槽进行了现场试验,并安设顶板离层仪等矿压观测设备进行效果验证。观测数据显示预应力全长锚固锚杆(索)支护技术可有效控制冲击地压矿井沿空顺槽巷道围岩变形,提高巷道稳定性。In order to verify the application effect of prestressed full-length anchoring anchor rod(cable)and other support technology in gob-side driving roadway of rock burst mine,field tests were carried out in the 5304 working face track grooving of Zhaolou Coal Mine,and set up roof separation meter and other mine pressure observation equipment to verify the effect.The observation data show that the prestressed full-length anchoring anchor rod(cable)support technology can effectively control the surrounding rock deformation of roadway along goaf in rock burst mine and improve the stability of roadway.
