摘要
通过分析煤矿常用的几种锚杆支护理论,结合某煤矿巷道具体地质条件,确定了各种锚杆支护理论机制下的锚杆支护方案,计算出了锚杆支护参数,并将各种方案应用于巷道支护。经过观测,模拟对比分析巷道帮部和顶板变形量大小,确定了适用于具体巷道的锚杆支护参数。
Through the analysis of several theory of bolt support commonly used in coal mine,combined with the specific geological conditions of the roadway,the bolt support schemes and the parameters were respectively determined by various bolt support theories.By comparing the supporting effects of different support schemes,the reasonable bolt support parameters for specific roadway were determined.
