陈削式回转钻机是一种小型钻机,可使用切削式钻头加潜孔冲击器或切削式钻头加牙轮钻头,适用于软岩及不耐磨的中硬岩。切削式回转钻机适用范围取决于岩石的抗压强度和二氧化硅含量的多少,岩石耐压强度不大于2500～3000公斤力/厘米~2和SiO_2含量不高于7％可使用切削式钻头(据日本采石手册),超过这个范围,在硬岩和极硬耐磨岩石
The Drill Rotary Drilling Rig is a small drill that can be used with either a cutting bit plus a downhole impactor or a cutting bit plus a roller bit for soft rock and hardwearing medium hard rock. Cutting rotary drilling rig depends on the scope of rock compressive strength and the amount of silica content, rock compressive strength of not more than 2500 ~ 3000 kg / cm ~ 2 and SiO2 content of not more than 7% can be used cutting bit ( According to the Japanese quarry manual), beyond this range, hard rock and extremely hardwearing rock
