摘　　要：根据唐口煤矿以往的工程实践和现有的支护材料提出了多个锚杆(索)联合支护方案,分别对比锚杆(索)排距、锚索间距对支护效果的影响。通过数值模拟的手段确定了合理的锚杆(索)排距为1 000 mm,锚索间距为1 000 mm。根据确定的支护密度,形成了最优支护方案。According to Tangkou coal mine＇s previous engineering practice and available support material, proposing six support programs. These programs are used to compare the influence of row and low space to support effect. Based on results of numerical simulation, the reasonable row and low space is 1 000 mm×1 000 ram. So the reasonable support program is obtained.
