Description
Technical field
The utility model is related to technical field of coal mine equipment, more particularly to a kind of comprehensively monitoring coal seam drill fire extinguishing dress
Put.
Background technology
During underground coal mine is drilled, it is the serious disasters and accidents for influenceing coal miner life security that drilling, which is caught fire, to state
Family's property and people's life's health are brought about great losses, and larger adverse effect is brought to Safety of Coal Mine Production work.
At present, row's powder mode of colliery construction drill mainly have wind row powder, water row's powder and from row's powder (including dry row's powder and
Add wet row's powder two types of water in drilling in right amount) three basic forms of it.Wherein：Wind arranges the colliery construction drill technique of powder mode
Firing accident easily occurs；The firing accident that drills may occur for the colliery construction drill technique of dry row's powder type；Water arranges powder mode
The firing accident that drills will not typically occur with from wet row's powder type colliery construction drill technique in row's powder mode.Therefore, below
Powder mode is arranged wind emphatically and the immediate cause from dry row's powder type colliery construction drill firing accident in row's powder mode is carried out
Initial analysis.
Wind row's powder mode construction drill firing accident has following several immediate causes：
First, drill bit or drilling rod continue to creep into after coming off, drill bit produces high temperature with drilling rod, drilling rod and drilling rod rubs mutually,
Simultaneously because into drilling air feed and possess Oxygen Condition, cause coal dust or gas combustion.
Second, continuing to creep into by force after bit freezing, top brill occurs, drill bit and the increase of coal seam frictional force produce high temperature, simultaneously because
The air feed into drilling and possess Oxygen Condition, cause coal dust or gas combustion.
Third, new and old drilling rod or the drilling rod of different model are used with, gap mismatches even slide fastener between drilling rod, causes drilling rod
Between phase mutual friction produce high temperature, simultaneously because into drilling air feed and possess Oxygen Condition, cause coal dust or gas combustion.
Fourth, drilling blast reduce, the row of causing powder it is unnet or drill inner powder amount it is excessive, simultaneously because into drilling air feed and
Possess Oxygen Condition, then meet high temperature, cause coal dust or gas combustion.
Immediate cause from dry row's powder type colliery construction drill firing accident in row's mode is：After being bored because of bit freezing or top
Continue the reason such as rubs mutually after drilling, drill bit or drilling rod come off by force and produce high temperature, cause high temperature coal dust, gas in drilling
Or after the compounding substances of the two are discharged out of hell, encounter oxygen and burn, or with igniting colliery construction drill operation
The combustibles such as the gas or coal dust of point, so as to which firing accident occur.
As can be seen here, how effectively drilling is caught fire during prevention is drilled turns into the key of prevention coal-mine fire accident,
Prevention colliery drill firing accident to Safety of Coal Mine Production work tool be of great significance.Study Period of Coal Seam Spontaneous Combustion synthesis
Prevention Technique and equipment are imperative.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome deficiency of the prior art, the utility model carries
Drilled fire extinguishing device for a kind of comprehensively monitoring coal seam.
Present China coal seam firing accident happens occasionally, and has plenty of caused by drilling, has plenty of caused by coal body spontaneous combustion, coal
The layer gas detected at first that catches fire is exactly CO gas, and smog of then being emerged out of drilling comes out, carbon monoxide gas
The harm that body once transfinites to people is very big.Thus once coal seam is drilled on fire, carbon monoxide transducer alarm or
Smoke Sensor alarm after, the miner of field operation can typically flee the scene in the very first time, but scene the condition of a fire still, fire
It can always burn, can spread, can develop, be also possible to that secondary disaster occurs when running into methane gas.So in this case,
With regard to being badly in need of, required a set of self-extinguishing processing unit carrys out the very first time and knows that disaster, the very first time handle disaster scenarios it.
1st, CO gases can be all produced because drilling to catch fire, in in-site installation CO sensors of drilling, live CO gas concentrations transfinite
Alarm signal is sent (as set actuation of an alarm concentration as 24PPm), and information is reached into outstation.Sensed using carbon monoxide
The alarm signal that device provides, substation main frame reception signal realize the control to circuit breaker, and circuit breaker receives substation host computer control life
Order, to control electrical ball valve to power off or be powered, realize automatic water jetting.
2nd, smog can be all produced because drilling to catch fire, in in-site installation Smoke Sensor of drilling, live Smoke Sensor detection
Go out smog and send alarm signal, and information is reached into outstation.The alarm signal provided using Smoke Sensor, outstation
Reception signal, realizes the control to circuit breaker, and circuit breaker receives outstation control command, to control electrical ball valve to power off or
It is powered, realizes automatic water jetting.
Carbon monoxide transducer, Smoke Sensor and outstation rated operational voltage should be with monitoring mining monitoring system electricity
Pressure matches.Circuit breaker and electrical ball valve rated operational voltage should match with mine illuminating system voltage.Outstation can be real
Now more place automatic sprinkler controls.
After carbonomonoxide concentration transfinites or smog occurs, automatic water jetting, rig air feed is automatically stopped, automatically cuts off brill
Electromechanical source, from trend pouring water into borehole.After carbonomonoxide concentration recovers normal and scene does not have smog, coal seam is drilled fire extinguishing
Device will still keep water spray, blowing-out, power-off, the charging state into drilling, only after manual rotation's rotary switch, can recover former
Beginning state.
