Shotcreting
technology,a
primary
method
for
roadway
bolt-shotcrete
support,is
now
widely
applied
in
mine
excavation
support. Dust
is
generated
during
shotcreting
operations,including
handling,feeding,mixing,and
spraying
stages,making
it
one
of
the
main
dust
sources
in
mining. For
current
research
on
shotcreting
dust
control
technologies,quantitative
analysis
of
literature
over
the
past
50
years
was
conducted
using
CiteSpace
software. Research
hotspots
were
categorized
and
statistically
analyzed
in
terms
of
publication
volume, authors, institutions, keyword
co-occurrence, clustering, and
time
zones. Research
shows
that
China′s
research
on
shotcreting
technology
started
relatively
late,with
its
development
showing
phased
characteristics:①
Embryonic
exploration
stage,in
the
1970s,breakthroughs
were
made
in
the
development
of
shotcrete
equipment. Shotcreting
technology
gradually
found
application
in
mine
roadways
and
slope
support,but
the
technology
and
equipment
remained
immature. ②
Growth
and
development
stage,in
the
1980s,wet
spraying
technology
began
to
be
promoted. However,due
to
insufficient
emphasis
on
safe
operation,severe
dust
hazards
and
frequent
production
accidents
occurred. ③
Mature
growth
stage,
in
the
early
21st
century,the
state
introduced
clear
legislation
on
work
safety
and
occupational
diseases. The
dust
problem
in
shotcreting
operations
thus
received
sustained
attention
and
research
from
scholars
in
the
field,driving
the
development
of
shotcreting
dust
control
research. After
2010,improving
the
practicality
of
shotcreting
machines
became
the
focus,with
a
rapid
increase
in
the
number
of
related
publications. ④
Epidemic-induced
downturn
stage,from
2018
to
2022,the
number
of
publications
declined
significantly
due
to
the
impact
of
the
epidemic
and
research
cycles. However,long-term
projections
suggest
that
research
in
shotcreting
dust
control
still
has
substantial
room
for
expansion
in
breadth
and
depth,with
growing
attention. Core
authors
maintain
extensive
collaborative
relationships,while
non-core
authors
are
widely
distributed
and
highly
independent.
Research
teams
in
shotcreting
dust
control
are
mainly
composed
of
universities
and
colleges,with
no
extensive
collaboration
formed
among
institutions
across
regions. Both
authors
and
institutions
in
English
literature
overlap
significantly
with
those
in
Chinese
literature. Domestic
scholars
focus
more
on
engineering
applications,whereas
foreign
scholars
mainly
emphasize
areas
such
as
the
laws
of
wet
concrete
pipeline
transportation
and
jet
structure
characteristics. Keyword
evolution
indicates
that
the
existing
research
is
moving
toward
in-depth
exploration
of
optimizing
shotcreting
equipment
and
applying
shotcrete
in
new
materials
and
environments,with
an
increasing
number
of
research
directions. On
this
basis,current
challenges
in
shotcreting
dust
control
research
are
further
discussed,along
with
future
development
trends. Key
challenges
in
this
field
include
clarifying
dust
generation
and
reduction
mechanisms
in
shotcreting,developing
intelligent
and
precise
wet
shotcreting
technologies,creating
portable
shotcreting
equipment,strengthening
vocational
training
for
technical
workers,expanding
research
teams,and
enhancing
collaborative
development
and
research
among
industry,academia,research,and
application. Future
research
on
mine
shotcreting
dust
control
can
be
deepened
through
measures
such
as
clarifying
dust
generation
and
reduction
mechanisms
via
various
experiments
and
numerical
simulations,developing
precise
dust
control
schemes
by
integrating
emerging
intelligent
technologies
like
artificial
intelligence
and
machine
vision,strengthening
research
on
drag
reduction
in
long-distance
material
pipeline
transportation
and
dust-free
jet
theory,expanding
shotcreting
dust
prevention
applications
across
multiple
fields
and
industries,and
promoting
standardization
of
shotcreting
dust
prevention
and
control.
