Gas unit: gas is the formidable enemy of Safety of Coal Mine Production, have many collieries that gas explosion occurs every year, cause casualties, mine is seriously damaged.In order to prevent gas exceeding limit, blast, native system can utilize methane transducer automatically to monitor face gas concentration.Air-blower control relay group 13 is made up of three relays, respectively three electromagnetic valves of corresponding 19, composition three times' lifting.When gas density reaches default concentration, system can automatically start high-pressure air hose opening and closing electromagnetic valve 19 and report to the police, and opens one-level and adds blast, open high-pressure air hose and dispel face gas, effectively reduce gas density of meeting head on.When a certain setting value of gas density reduction system, 19 close, and close high-pressure air hose.If gas density is not fallen or is increased under one-level pressurized condition, system can Controlling solenoid valve carry out secondary or three grades add blast.Meanwhile, for the spark ignition preventing mechanical friction, spoil collision etc. from producing causes gas explosion, system can utilize 14 controls 21 to open high-pressure water pipe to carry out mist cooling, and after high-pressure air hose is closed, high-pressure water pipe spraying is also closed immediately.If face gas outburst amount is excessive, when above-mentioned measure can not reduce gas density, according to " Safety of Coal Mine Production regulation ", when gas density is more than 1.5%, system drive J5 controls mining feed switch, stops powering to work plane.But because this system adopts the mining ups power case of a set of Flameproof and intrinsically safe to power, high pressure air feed and spraying also can continue unlatching 4 hours, for follow-up process is laid the groundwork.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Carbon monoxide unit: carbonomonoxide concentration exceeds standard and staff's anthracemia not only can be caused dead, and also has the danger of blast.Therefore, work plane is also the most important thing to the monitoring of carbon monoxide, control.The carbon monoxide transducer collection of carbonomonoxide concentration by installing, judges through system, adopts the measure identical with above-mentioned gas exceeding limit when reaching setting concentration.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Carbon dioxide unit: in process of coal mining, personnel breathe, fuel oil machinery equipment operation, spontaneous combustionof coal generate heat, and all can produce carbon dioxide, if staff can be caused to have difficulty in breathing in air feed deficiency in small space of meeting head on.This unit is by carbon dioxide sensor collection site data, and operating principle is identical with above-mentioned two kinds of unit.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Temperature unit: in process of coal mining, machine operation, coal seam heating all can cause work plane temperature to raise, and add potential safety hazard.When temperature pick up collects temperature data higher than default value, system controls 21 by 14 and carries out mist cooling, closes spraying when reaching a certain desired temperature.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation.According to permeable omen, when system monitoring declines suddenly to work plane temperature, to ore deposit side due to temperature variations, provide the hydrology on the other hand data, be also colliery permeable give photograph
Dust unit: dust (coal dust, cash dirt) is the most important dangerous matter sources in colliery.When there is gas explosion or fire, also can explode if coal dust exceeds standard, the safety in the healthy and colliery of workman in serious harm simultaneously.Under workers with long time is operated in dust atmosphere simultaneously, be easy to obtain pneumoconiosis, this is also the modal occupational disease of coal miner, and serious harm miner is healthy.For this situation, native system controls dust-removing blower for mine make and break contact by 15, when the face dust concentration of dust sensor collection is greater than default concentration, system can open dedusting fan depositing dust automatically, and open water spraying is simultaneously until dust concentration closes dedusting fan and water spray after being less than a certain setting value.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Smoke units: in working face mining process, because spontaneous combustion of coal seam, mechanical wear, electric cable heating all can produce smog.Containing a large amount of pernicious gas in smog, harm workers ' health.This system utilizes Smoke Sensor collection site smokescope, and control 21 open water fog spray heads by 14 after reaching default value and reduce smokescope, simultaneity factor can utilize 19 unlatching one-levels to add blast, accelerates to reduce smokescope.After smokescope is reduced to a certain setting value, system closes 19 and 21 automatically.Above-mentioned situation all can be transferred to ground monitoring center with 485 communication modes through underground communica tion substation, accomplishes that omnibearing stereoization is protected.
Nearly body protected location: native system has installed far infrared nearly body protection sensor; when there are personnel in plant equipment front; Systematical control 15 links plant equipment make and break contact, makes it not drive or to stop in emergency, effectively avoids coal-winning machine, situation generation hurted sb.'s feelings by development machine.
This detailed description of the invention has following beneficial effect: it is for prior art defect; a set of automation protect system is devised to mining face under mine; solution coal mine downhole safety is produced; prevent gas explosion, coal-dust explosion, anthracemia, machinery from hurting sb.'s feelings; reduce dust in recovery process and, to the injury of staff, prevent the problems such as calm operation.
