摘　　要：为了解决大木厂煤业特厚煤层沿底板全煤巷道支护难题,分析了煤岩体地质力学参数测试结果,掌握特厚煤层地应力和煤岩体强度特征,模拟研究了不同锚固长度下锚杆(索)锚固效果,设计了锚杆和锚索锚固性能试验方案,并在井下进行试验。试验结果表明,特厚煤层沿底板全煤巷道适合采用锚杆支护技术,并根据井下应用环境,提出了相应的改进措施。In order to solve the support difficult problem of coal roadway along the bottom of extremely thick coal seam, the coal and rock mass geological mechanics parameters test result is analyzed, the coal and rock mass stress and ground stress characteristics are mastered , the anchoring effect is simulated and studied with different anchorage length of bolt and anchor cable, anchoring performance test plan is designed and tested in the underground. The test results shows that the bolt support technology is Suitable for the coal roadway along the bottom of extremely thick coal seam, according to the application environment, the corresponding measures are put forward.
