摘要
三交河煤矿采用高预应力、强力锚杆与锚索支护方式,实现了锚杆的主动及时支护,大幅减少了巷道围岩变形,巷道支护与安全状况有了质的改进。这种高强度、高刚度、高可靠性、低支护密度的"三高一低"现代锚杆支护设计理念,具有良好推广前景。
In Sanjiaohe mine, high pre-stress, strength bolt and cable support are adopted to realize the initiative and timely supporting, which decreases the surrounding rock deformation and improves the roadway support and safety situation. The technology has a bright future for spreading with the modem supporting concepts as high strength, high stiffness, high reliability, and low support density.
