preparing entry

Based on the experiment by using split rockbolt support at Peifeng Mine Yanwu +35m-21#,Fujian Coal and Electricity Corporation,the paper proves that split rockbolt support in developing entry has advantages over the traditional support and other rockbolt supporting types.

通过对福建煤电公司培丰煤矿延五+35m-21#运巷进行缝管式锚杆支护试验,证明缝管式锚杆支护相对于采准巷道的传统支护方式及其他类型锚杆支护有较大优势,是一种支护及时、经济有效的新型锚杆支护形式,是采准巷道支护改革的一个方向。
