就牙轮钻孔的诸要素进行了论述，探讨了最佳钻进的诸多影响因素和实现途径。给出了最大及最佳轴压力的经验确定方法以及钻头类型选择依据；就钻头上的最大回转速度进行了分析讨论；论述了炮孔排碴、司机操作、钻机自动化程度和钻机综合性能对钻孔效果的影响；探讨岩石平均抗压强度，应用岩石力学数据做为寻求最佳钻进的出发点，为钻机设计及实际操作提供依据。
Discusses the elements of roller cone drilling and discusses many influencing factors and ways to realize the optimal drilling. The method of determining the maximum and optimum axial pressure and the selection of the type of the drill bit are given. The maximum rotational speed of the drill bit is analyzed and discussed. The effects of blasting, driver operation, degree of automation of the drilling rig and drilling rig performance on drilling Hole effect; to explore the average compressive strength of rock, rock mechanics data as a starting point for seeking the best drilling, drilling rig design and provide the basis for the actual operation.
