Description
Technical field
The invention belongs to mineral engineering field, and in particular to one kind is without coal pillar mining lane side obturator and its construction
Method.
Background technology
, it is necessary to tunnel at least two tunnels, form pressure on the rib of both sides after exploitation increases the traditional arrangement of working face
High region, easily trigger the dynamic disasters such as bump, coal and gas prominent, therefore set enough between traditional working face with staying
Protection coal pillar solve problems.Without coal pillar mining technology, no coal pillar mining is not only realized, it is also pre- using advanced explosion
The technology directly pushed up is split, improves the stress distribution around stope.This method is to be caving self-contained lane side using what is directly pushed up, because
Pernicious gas passage between this isolation goaf and tunnel is the key for solving safety in production.Traditional slip casting wastes largely
Goods and materials, and can not meet the plasticity requirements to crush, existing flexible encapsulated, flexible material is in the complicated operation ring in underground
Phenomena such as easily being scratched in border, the joining place between material can not ensure absolutely not to leak out, and can not meet fluctuations compared with
Big top plate.
The content of the invention
Opened in view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing one kind without coal column
Lane side obturator and its construction method are adopted, solves to waste time and energy in prior art construction, sealing effectiveness is poor, material property difference
Defect.
The present invention uses following technical scheme：
One kind is described to keep off the upper and lower of cash post without coal pillar mining lane side obturator, including spaced some gear cash posts
Both ends are respectively arranged with top girder steel and lower steel belt, and the side in goaf is provided with gear cash net, institute in the gear cash post
State gear cash and be provided with flexible cloth on the net, the flexible cloth upper end is fixed by keeping off cash post and top girder steel with crossheading top plate, institute
The bottom for stating flexible cloth is fixed by keeping off cash post and lower steel belt with crossheading bottom plate.
Further, gear cash net side surface spraying has hermetic flexible material.
Further, the hermetic flexible material is the inorganic material being made up of base-material addition fire retardant.
Further, it is bonded and is fixed by band between the gear cash net and flexible cloth.
Further, the flexible cloth is to be combined by macromolecule waterproof ventilative material plus cloth.
A kind of construction method of no coal pillar mining lane side obturator, comprises the following steps：
S1, flexible cloth and gear cash net fitting fixed；
S2, by flexible cloth side towards goaf, flexible cloth upper end is fixed on crossheading by keeping off cash post and top girder steel
Top plate；Flexible cloth bottom is fixed on crossheading bottom plate by keeping off cash post and lower steel belt；
S3, hermetic flexible material is injected in the side surface of gear cash net one, completes construction.
Further, after the completion of step S3, treat that goaf spoil is stable, after deformation of crushing, to step S3 surface
Carry out the second gunite.
Compared with prior art, the present invention at least has the advantages that：
The present invention is without coal pillar mining lane side obturator, including spaced some gear cash posts, and is arranged on gear cash
The top girder steel and lower steel belt of post upper and lower ends, the side in goaf is provided with gear cash net in gear cash post, gear cash is online
It is provided with flexible cloth and is used for closed, is aided with gear cash net support, the air channel completely cut off between goaf and tunnel, securely and reliably, work
Skill is simple, and mechanized construction substantially increases efficiency.
Further, keeping off cash net side surface spraying has hermetic flexible material, closed using two layers of flexible cloth and whitewashing body,
Closed intensity is improved, extends service life.
The invention also discloses a kind of construction method of no coal pillar mining lane side obturator, by flexible cloth and gear cash net patch
Close and fix, by flexible cloth side towards goaf, flexible cloth upper end is fixed on crossheading top plate by keeping off cash post and top girder steel；
Flexible cloth bottom is fixed on crossheading bottom plate by keeping off cash post and lower steel belt, hermetic flexible material is finally injected in gear cash
The side surface of net one, completes construction, and pulp shooting machine is adopted hermetic flexible material spraying in gear cash net, whole construction by slurry pipeline steel pipe
With mechanized operation, speed of application is fast, low cost, hermetic flexible material adsorptivity are strong, and flex capability is good, meets mine safety height
Imitate the demand of production.
In summary, structure entirety plasticity of the present invention is stronger, meets roof deformation requirement, directly keeps off cash net using existing,
And gear cash post reusing, greatly reduce cost.
Below by drawings and examples, technical scheme is described in further detail.
Brief description of the drawings
Fig. 1 is construction effect sectional view of the present invention；
Fig. 2 is I-I visual angles schematic diagram in Fig. 1.
Wherein：1. keep off cash net；2. flexible cloth；3. keep off cash post；4. top girder steel；5. band；6. pulp shooting machine；7. slurry pipeline steel
Pipe；8. hermetic flexible material；9. lower steel belt；10. goaf.
Embodiment
