  • 摘要: 针对煤矿巷道锚固孔快速精准钻进的施工需求,通过建立PDC锚杆钻头回转钻进力学模型,对其主要力学影响因素进行了理论分析。结果表明:PDC切削齿轴向力随压入深度的增大而增大,随切入角的增大表现出先减小后增大的趋势;当煤系岩石摩擦系数f为0.20~0.43时,可得最优切入角为15.0°~18.3°,此时在相同压入深度条件下轴向力和切向力最小。并进一步结合煤系岩石的力学特性,提出了PDC切削齿作用下的岩石破碎条件,得出不同压入深度时轴向力和切向力的关系。利用自主研发的钻进试验台对模拟岩样进行了钻进试验,试验结果验证了PDC锚杆钻头回转钻进力学模型的正确性。研究结果为PDC锚杆钻头优化设计,锚固孔钻进效率与精度的提高,以及钻进轴向力和切向力的变化预测等提供了理论依据。
