Abstract
The present invention relates to underground coal mine fire dam, it is specially underground coal mine environment-friendly type inflated type fire dam, solve the problem that existing underground airtight wall efficiency of construction is low, be not easy to dismounting, not reusable edible, the technical solution used in the present invention is: underground coal mine environment-friendly type inflated type fire dam, including multiple inflation cylinders, described inflation cylinder bottom is provided with inflation inlet, and described inflation inlet is provided with Pressure gauge and safety-valve, and described each inflation column side face longitudinal arrangement is fixed with multiple connection collar.The invention have the advantages that 1, cost of manufacture cheap；2, installation, convenient disassembly fast, substantially increase work efficiency；3, reusable edible after inflation venting, reduces production cost.
Description
Technical field
The present invention relates to underground coal mine fire dam, specially underground coal mine environment-friendly type inflated type fire dam.
Background technology
Along with the increase of the seam mining degree of depth, stope is constantly pushed ahead, and the scope in goaf constantly expands, and makees
The Large Coal Enterprises problem that gas is big when producing for mechanization full-seam mining is easier to manifest.Dilute for ensureing sufficient air quantity
Releasing gas, part mine uses double lanes driving at driving face, and stope uses the ventage of " three enter twice " Y type partially
System is smooth Production Cohesion simultaneously and makes full use of existing tunnel, and work surface needs to retain two tunnels in exploitation process and is
Next work surface service, this is accomplished by between enclosing tunnel horizontal river for completely cutting off and regulating distinguished and admirable.At present, underground coal mine contact horizontal stroke
Build fire dam in river mainly to use, construct the traditional means way combined with concrete spraying with masonry.This traditional
Although material has the advantages such as certain resistance to compression and impact resistance, but this hard fire dam there is also backward in technique, construction effect
The unfavorable factors such as rate is low, waste of material, and affected by ground pressure and easily damage cracking, threaten neighbouring personnel and equipment safely.
It addition, masonry substantially can not reuse after dismounting with concrete hard material, make also can to space, down-hole and transport
Become burden.Therefore, designing the security closed wall that a kind of quick construction is convenient, be easy to remove, can be recycled is extremely to be necessary
's.
Summary of the invention
The present invention solves the problem that existing underground airtight wall efficiency of construction is low, be not easy to dismounting, not reusable edible,
A kind of underground coal mine environment-friendly type inflated type fire dam is provided.
The present invention is achieved by the following technical solutions: underground coal mine environment-friendly type inflated type fire dam, fills including multiple
Gas column body, described inflation cylinder bottom is provided with inflation inlet, described inflation inlet is provided with Pressure gauge and safety-valve, described each
Inflation column side face longitudinal arrangement is fixed with multiple connection collar.Multiple inflation cylinders are longitudinally disposed is arranged in body of wall, can close
Jian Heng river, tunnel, is used for completely cutting off and regulating distinguished and admirable.Pressure gauge and safety-valve are installed on inflation inlet, are used for monitoring in inflation cylinder
Pressure, when exceeding safe pressure, in safety-valve disappointing guarantee inflation cylinder, pressure is in safety range, keeps the most simultaneously
Degree.Each inflation column side face longitudinal arrangement fixes multiple connection collar, and available iron wire is by the connection collar string between inflation cylinder
After being connected together, body of wall or pillar with both sides, tunnel are fixed, and prevent from inflating cylinder lodging.
Have on described inflation cylinder along inflating the tune air regulator that cylinder is the most through.Adjust air regulator that appropriate wind can be allowed through filling
The fire dam that gas column body is arranged in, it is ensured that certain ventilation.
The invention have the advantages that 1, cost of manufacture cheap；2, installation, convenient disassembly fast, substantially increase work
Efficiency；3, reusable edible after inflation venting, reduces production cost.
Accompanying drawing explanation
Fig. 1 is that the present invention inflates cylinder monomer structure front view；
Fig. 2 is that the present invention inflates cylinder monomer structure left view；
Fig. 3 is scheme of installation of the present invention；
In figure: 1-inflates cylinder, 2-inflation inlet, 3-safety-valve, and 4-connects the collar, and 5-adjusts air regulator.
Detailed description of the invention
Underground coal mine environment-friendly type inflated type fire dam, including multiple inflation cylinders 1, described inflation cylinder 1 bottom is provided with to be filled
QI KOU 2, described inflation inlet 2 is provided with Pressure gauge and safety-valve 3, and described each inflation cylinder 1 side longitudinal arrangement is fixed
There is multiple connection collar 4.
When being embodied as, described inflation cylinder 1 has along inflating the tune air regulator 5 that cylinder is the most through.
During use, needing the top board arranging in the horizontal river of fire dam and portion of side to draw to dig out the ditch of one fixed width and the degree of depth
Groove, groove width is identical with inflation cylinder 1 maximum gauge.Then inflation cylinder 1 is arranged in groove, leads to plenum pump
Overcharge QI KOU 2 to inflate to each inflation cylinder 1, observe Pressure gauge and ensure that pressure is less than margin of safety.Then will be each with iron wire
The connection collar 4 between individual inflation cylinder 1 is together in series, and fixes with Heng Chuan both sides body of wall, prevents inflating cylinder 1 and lodges.Then
Whitewashing leak stopping on gap between groove periphery and inflation cylinder 1, it is ensured that the closing of fire dam.After use, open inflation
Safety-valve 3 on mouth 2, discharges gas, removes the iron wire connected on the collar 4, the most dismountable temporary airtight wall, inflates cylinder
1 also can be recycled.
