METHOD OF DRILLING UNIT CONTROL AND DRILLING UNIT

摘要

mining, particularly, drilling with possible change of its direction. SUBSTANCE: method provides for deviation of drilling head from straight line in preset direction found at an angle to straight line. Such deviation is attained due to pressing of drilling head by axial force when cutting member of drilling head is found on cutting curve through which beam of preset direction of deviation of drilling head passes. When cutting member is found beyond the cutting curve, drilling head is withdrawn back. EFFECT: higher accuracy of drilled hole direction control. 24 cl, 10 dwg
