... that for safety and efficiency of the mining operation, the velocity of the mining machine and the nodule mass should be limited within appropriate ranges (about 0.3–0.5m/s and 2000–4000kg) and the countercurrent mining operation should be avoided in the case of smaller wave period. INTRODUCTION With the rapid...
