摘　　要：作为一种实用的支护形式,锚杆支护主要改善井巷围岩力学性能,充分利用了井巷围岩自身的承受力与强度,因此其属于主动型的支护结构。锚网支护、喷射混凝土支护、锚杆支护以及锚杆注浆支护等均属于常见的支护形式。分析了某煤矿的地质条件,根据其综放开采特点指出了锚杆支护的实际方法,并针对该矿大断面综采巷道锚杆支护提出了合理化建议。As a practical support form,bolt support mainly improves the mechanical properties of surrounding rock,and makes full use of the bearing capacity and strength of surrounding rock. So it belongs to active support structure. Bolt net support,shotcrete support,bolt support and bolt grouting support are common support forms. This paper analyses the geological conditions of a coal mine,points out the practical method of bolt support according to the characteristics of fully mechanized caving mining ,and puts forward reasonable suggestions for bolt support of large cross-section fully mechanized mining roadway in this mine.
