	%X Underground tunnel face bolting and pipe umbrella
reinforcement are one of the most challenging tasks in construction
whether industrial or not, and infrastructures such as roads or
pipelines. It is one of the first sectors of economic activity in the
world. Through a variety of soil and rock, a cyclic Conventional
Tunneling Method (CTM) remains the best one for projects with
highly variable ground conditions or shapes. CTM is the only
alternative for the renovation of existing tunnels and creating
emergency exit. During the drilling process, a wide variety of
non-desired vibrations may arise, and a method using a robot arm
is proposed. The main kinds of drilling through vibration here is the
bit-bouncing phenomenon (resonant axial vibration). Hence, assisting
the task by a robot arm may play an important role on drilling
performances and security. We propose to control the axial-vibration
phenomenon along the drillstring at a practical resonant frequency,
and embed a Resonant Sonic Drilling Head (RSDH) as a robot end
effector for drilling. Many questionable industry drilling criteria and
stability are discussed in this paper.
