摘　　要：锚注支护利用空心锚杆兼做注浆管,通过注浆将松散围岩胶结成整体,既提高了围岩自身的承载能力,又为锚杆提供了可靠的着力基础,从而有效地控制了深部软岩巷道及硐室的大变形,尤其对松软破碎岩体的支护极为有效。The bolt - grouting support uses the honow bolt as the grouting pipe, cemented the looses surrounding rocks into a whole by grouting, improves the carrying capacity of the surrounding rocks, and provides reliable force basis for the bolt＇ s anchoring effect, thus effectively controls the large deformation of the deep soft - rock roadway and chamber, especially effective for the supporting of the soft broken rock.
