8인치급 다운더홀(DTH) 해머의 모델링 및 설계인자에 따른 영향도 분석

Rock drill equipment which top hammer, down-the-hole hammer and rotary drill is used as a representative in accordance with the strike and drive type of the drill. in this paper, Due to the characteristics of underground drilling of work conditions it is difficult to obtain the experimental data. So modeling and Analyzing the down-the-hole hammer through simulation software AMESim and Among the design parameters using the design of experiment selected for the factors affecting the Strike energy and BPM and analyzed influence by each design factors.
