锚喷支护是最有效、最经济的巷道支护形式之一。目前的井巷工程实践证明，除特殊情况，锚喷支护技术几乎可以用于所有岩土工程的围岩加固。纵观其发展史，锚杆主要分为两代：第1代以砂浆钢筋或钢丝绳锚杆为代表；第2代以水泥药卷和树脂钢筋锚杆为代表。按锚杆与被加固岩体的锚
Anchor spray support is the most effective and most economical form of roadway support. The current practice of shaft engineering proves that except for special circumstances, the technology of bolt and shotcrete can be applied to almost all the surrounding rock reinforcement of geotechnical engineering. Throughout the history of its development, the anchor is divided into two generations: the first generation represented by mortar rebar or steel wire anchor; the second generation represented by cement roll and resin reinforced anchor. Anchor by anchor and reinforced rock mass
