Gas unit：Gas is the formidable enemy of Safety of Coal Mine Production, has many coal mines that gas explosion occurs every year, causes
Casualties, mine are seriously destroyed.Gas exceeding limit, explosion in order to prevent, this system can utilize methane transducer automatic
Monitoring face gas density.In Fig. 3 multistage air feed structure diagrams, multistage air feed controls relay group 13 by three relays
Composition, corresponds to three solenoid valves of high-pressure air hose opening and closing solenoid valve block 19 respectively, and composition three-level adds wind pressure.When gas density reaches
During default concentration, system can start high-pressure air hose opening and closing solenoid valve block 19 and alarm automatically, open level-one solenoid valve and add wind
Pressure opens high-pressure air hose and dispels face gas, effectively reduces gas density of meeting head on.When gas density reduces, system is a certain to be set
During definite value, 19 are closed, and close high-pressure air hose.If gas density is not dropped or increased under level-one pressurized condition, system can be controlled
Two level or three-level solenoid valve processed carries out two level or three-level adds wind pressure.Meanwhile the fire to prevent the generations such as mechanical friction, spoil collision
Flower, which is lighted, causes gas explosion, and system can open high-pressure water pipe using 14 controls 21 and carry out mist cooling, when high-pressure air hose is closed
Afterwards, high-pressure water pipe spraying is also closed immediately.If face gas outburst amount is excessive, above-mentioned measure cannot reduce gas density
When, according to《Safety of Coal Mine Production provides》, when gas density is more than 1.5%, system drive 17 controls mining feed switch, stops
It powers to working face.But since the system is powered using the mining ups power case of a set of Flameproof and intrinsically safe, high pressure air feed and
Spraying can also continue to open 4 hours, lay the groundwork for subsequent processing.The above situation can all be led to 485 communication modes by underground
Letter substation is transferred to ground monitoring center, accomplishes that omnibearing stereoization is protected.
Carbon monoxide unit：The exceeded staff's anthracemia that not only results in of carbonomonoxide concentration is dead, and
The danger also exploded.Therefore, working face is also the most important thing to monitoring, the prevention of carbon monoxide.Carbonomonoxide concentration passes through
The carbon monoxide transducer 4 of installation acquires, and judges by system, using identical with above-mentioned gas exceeding limit when reaching setting concentration
Measure.The above situation all can be transferred to ground monitoring center with 485 communication modes by underground communica tion substation, accomplish comprehensive vertical
Bodyization is protected.
Carbon dioxide unit：In process of coal mining, personnel's breathing, the fever of fuel oil machinery equipment operation, spontaneous combustionof coal, all
Carbon dioxide can be generated, if air feed deficiency can cause staff to have difficulty in breathing in small space of meeting head on.The unit is by two
5 collection site data of carbon sensor are aoxidized, operation principle is identical with above two unit.The above situation all can be with 485 communication parties
Formula is transferred to ground monitoring center by underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Temperature unit：In process of coal mining, machine operation, coal seam fever can all cause working face temperature to increase, and increase
Security risk.When temperature sensor collects temperature data higher than default value, system is sprayed by 14 controls 21
Mist cools down, and spraying is closed when reaching a certain desired temperature.The above situation all can pass through underground communica tion substation with 485 communication modes
It is transferred to ground monitoring center.According to permeable omen, when system monitoring declines suddenly to working face temperature,.To ore deposit side due to temperature
Spend situation of change, provide hydrology proficiency data and coal mine it is permeable give photograph
Dust unit：Dust（Coal dust, cash dirt）, it is the most important danger source of coal mine.When gas explosion or fire occurs,
If coal dust is exceeded also to explode simultaneously, worker's health and the safety of coal mine are seriously endangered.Workers with long time work simultaneously
Under dust atmosphere, it is easy to obtain pneumoconiosis, this is also the most common occupational disease of coal miner, seriously endangers miner's health.Needle
To such case, this system is by 15 control dust-removing blower for mine make and break contacts, when the working face dust that dust sensor 7 acquires
When concentration is more than default concentration, system can automatically open dedusting fan depositing dust, while open water spray until dust concentration
Less than closing dedusting fan and water spray after a certain setting value.The above situation all can be with 485 communication modes by underground communica tion point
Station is transferred to ground monitoring center, accomplishes that omnibearing stereoization is protected.
Smoke units：During working face mining, since spontaneous combustion of coal seam, mechanical wear, electric cable heating can all generate smog.
Containing a large amount of pernicious gases in smog, workers ' health is endangered.The system utilizes smoke sensor device collection site smokescope, reaches
Smokescope is reduced by 14 control, 21 unlatching waterfog head after default value, simultaneity factor can utilize 19 unlatching level-ones to add
Wind pressure accelerates to reduce smokescope.After smokescope is reduced to a certain setting value, 19 and 21 are automatically closed in system.Above-mentioned feelings
Condition all can be transferred to ground monitoring center with 485 communication modes by underground communica tion substation, accomplish that omnibearing stereoization is protected.
Nearly body protection location：This system is mounted with the nearly body protection sensor 9 of far infrared, has personnel in front of mechanical equipment
When, system control 15 link mechanical equipment make and break contacts, prevent it from driving or stopping in emergency, effectively avoid coalcutter,
Development machine, which is hurted sb.'s feelings, to be happened.
Air hose monitoring unit：In existing coal production, single cave air supply of working face is using two fans, dual power supply, single cave air feed
Pipe aeration structure（Fig. 2）, undergone according to my years of work, but when main air blower power failure, maintenance or failure, standby fan has can
It can not start automatically or because air hose disconnects（Air hose section header damages）, tear, tunnel squeeze cause air hose deform after, all can
Cause air supply of working face insufficient or calm, according to《Safety of Coal Mine Production regulation》, the above situation forbids calm operation.For above-mentioned
Situation, staff want to withdraw working face, closely then hundreds of meters, far then several kms, belong to calm and withdraw, increase it is dangerous because
Element.For the above situation, which utilizes existing 2 contact of ram force sensor of air hose of meeting head on.The meeting when ram force is too low
It makes contact, which can receive contact current system, and multistage air feed control relay group 13 is driven to open high-pressure air hose opening and closing
Solenoid valve block 19 carries out working face multistage air feed.Back contact is replied when ram force to disconnect, height is automatically closed in system control 19
Pressure ventilation pipe.In addition, decompression nozzle 22 has a large amount of micropores, depressurization can be played, the unlatching for avoiding high-pressure air hose causes
Airborne dust problem of meeting head on.The above situation all can be transferred to ground monitoring center with 485 communication modes by underground communica tion substation, be
Troubleshooting of divulging information provides timely data.
Present embodiment has the advantages that：It is directed to prior art defect, and working face in the pit is devised
A set of automation protection system, solves coal mine downhole safety production, prevents gas explosion, coal-dust explosion, anthracemia, machine
Tool is hurted sb.'s feelings, the problems such as reducing injury of the dust to staff in recovery process, prevent calm operation.
