In this article have been shown the results of experimental research, completed at diamond drill stand in Irkutsk College of Technology, when drilling granite-porphyry. Based on the experimental results, the authors have established the dependence of absolute and relative wear of impregnated diamond bit on bit weight,revolutions per minute, watersupply and matrix hardness. Using the mathematical models of the bit wears, can be chosen optimal drilling parameters, suitable for optimal absolute...

本文阐述了在苏联伊尔库茨克工学院金刚石钻进试验台上钻进花岗斑岩时取得的试验研究结果。本文作者根据此试验结果确定出了金刚石孕镶钻头的绝对磨损、相对磨损与钻头压力、钻头转速、冲洗液量、胎体硬度的关系式。利用这些钻头磨损的数学模型就可确定出与钻头最优绝对磨损、相对磨损相应的最优规程参数来。

In this paper experimental research on dependence of penetration rate and power consumption for rock fragmentation upon drilling parameters is done in drilling marble and granite with experimental planning method by PDC crown. Mathematical models of the penetration rate and power consumption for rock fragmentation are obtained. Concepts of absolute power consumption and relative power consumption are suggested, considering that the later is more important than the former. Optimal drilling...

In this paper experimental research on dependence of penetration rate and power consumption for rock fragmentation upon drilling parameters is done in drilling marble and granite with experimental planning method by PDC crown. Mathematical models of the penetration rate and power consumption for rock fragmentation are obtained. Concepts of absolute power consumption and relative power consumption are suggested, considering that the later is more important than the former. Optimal drilling parameters on condition of minimum relative power consumption are calculated.

关于复合片钻头钻进大理岩和花岗岩时机械钻速和碎岩功率消耗同规程参数的关系,用实验设计方法进行了试验研究,得出了机械钻速和碎岩功耗与钻压、钻头转速及冲洗液量关系的数学模型;提出了碎岩绝对功耗和相对功耗的概念,而相对碎岩功耗是个更为重要的概念,求出了大理岩相对碎岩功耗最小时的最优钻进规程参数值。

ome problems about drilling highly vertical bord-holes with conventional drilling tools,including the constrction technic,were discussed and solved.The optimal drilling parameters were selected to apply successfully to the construction of the vertical bore-holes As a result ,the inclinations of the vertical bore-holes are all less than 0.035
