Grey Relation Analysis on the Sensitivity of Influencing Factors of Pneumatic DTH Hammer Drilling Efficiency

摘要:

分析了影响风动潜孔锤钻进效率的影响因素，利用实验数据建立了数学模型，然后根据灰色关联分析法对各影响因素进行敏感性分析，得到各个影响因素与钻进速度的关联程度。利用敏感性分析结果可以针对提高风动潜孔锤钻进效率采取科学措施，更有利于规范管理。

Abstract:

The factors that influence DTH hammer efficiency are analyzed and the mathematical model is established based on the experimental data. The sensitivity analysis is made on each influencing factor by grey relation analysis method to obtain the correlation degree of each factor and the drilling speed. By using the sensitivity analysis results, the scientific measures can be adopted to improve the drilling efficiency of pneumatic DTH hammer.
