Description
Technical field
This utility model relates to a kind of coal mine fully-mechanized mining coal-mining technique, particularly relates to a kind of longwell protrusive working face of coal seam machine
Xie Huawu lane exploitation complete set of equipments.
Background technology
At present, China's coal-mine is combined and is adopted in coal winning technology, and roadway workface is generally adopted by the method for driuing along goaf.Along empty
Driving is exactly in low stress field roadway layout, it is simple to roadway maintenance, reduces deflection, and it is it is crucial that strictly control coal column width
Degree, the purpose of future small coal pillar is to be isolated with goaf in tunnel, prevents the water in goaf and harmful gas from sealing in tunnel, jeopardizes peace
Full production, but its maintenance situation in tunnel is played a decisive role by coal pillar width, if coal column is too small, owing to the coal column by mined out side is propped up
The impact of load in moulding, easy unstability, wall caving is serious, if coal column is excessive, then layout of actual mining roadway is in pressure increases district,
Tunnel Pressure will be made big, supporting difficulty.
The process of driuing along goaf also exists serious defect and deficiency:
Exploitation cannot be reclaimed due to fender, cause coal resources waste；Due to the difference of various geological conditions, coal
The more difficult control of suitable size of post；Every work surface needs two tunnels of digging, and human and material resources consume huge；The standard in subsequent duty face
Standby workload is big, the time is long, affects coal mining efficiency.
Coal resources are disposable resource, and the response rate of coal resources is all paid much attention to by countries in the world, without coal pillar mining
The most therefore the research and development of edge air gallery technology arises at the historic moment.
Gob side entry retaining coal-mining technique is that former stope drift active workings are safeguarded at edge, coal-face tailing edge goaf.In order to reclaim tradition
Mining mode is stayed the safety pillar set, simultaneously in order to preferably safeguard that next adopts the tunnel in face, uses certain technological means
The crossheading supporting again of a upper section is left for next section use.This way staying lane is former along edge, goaf
The reservation of crossheading position is known as gob side entry retaining.
Gob side entry retaining is the maximally effective mining way currently without coal pillar mining, and it is more advanced than driuing along goaf mining type,
But the intrinsic deficiency that this technology is from principle design highlights day by day.Gob side entry retaining means to safeguard former back production lane along edge, goaf
Road, its premise is that first digging goes out tunnel, and this technology is only capable of few tunnel tunneling half than driuing along goaf, that is each work
One tunnel of face digging.
