DETECTING, EXCAVATING, SUPPORTING, ANCHORING AND
CONVEYING INTEGRATED MACHINE SYSTEM FOR DOWNHOLE
RAPID EXCAVATING AND USE METHOD THEREOF
FIELD OF THE INVENTION
[0001] The present invention relates to the technical field of mining
machinery, and in
particular to a detecting, excavating, supporting, anchoring and conveying
integrated machine
system for downhole rapid excavating and a use method thereof.
DESCRIPTION OF RELATED ART
[0002] With the increase of mining depth of production mine, a ground stress
and a surrounding
rock stress and deformation are complex and diverse. An anchor net support is
used by a
majority of tunnel mining, because of a good supporting effect, a wide range
of application,
flexibility in adapting to changes according to tunnel conditions, and other
features of the
anchor net support. However, in a current process of tunnel excavation, a
mechanized
excavation efficiency is very high, and a tunnel support speed lags far behind
an excavation
speed. Due to a serious mismatching of the excavating time, supporting time
and anchoring
time, a footage time of an excavating machine is far less than a total working
time, and in a
large amount of time, the excavating machine is shut down for performing a
support operation.
One direction to resolve the serious mismatch of the excavating time,
supporting time and
anchoring time is to implement an excavating, supporting and anchoring
parallel operation.
[0003] A patent entitled "UNMANNED TUNNEL EXCAVATING AND ANCHORING
INTEGRATED MACHINE" is disclosed in CN104500086A. A support system thereof
only
involves temporary support and anchor rod support, and cannot resolve a
problem of small
pieces of surrounding rock falling. If an anchor net needs to be installed, a
working section
needs to be manually approached, and a cutting head needs to be stopped for
safety of workers.
Therefore, the excavating, supporting and anchoring parallel operation cannot
be implemented,
and dust, noises and other factors also greatly threaten the safety of the
workers at the same
time. In addition, most of the existing technologies cannot carry out pre-
detection and do not
have an automatic anchor rod replacing mechanism. As a result, the safety is
not high and the
work efficiency is low.
