双鸭山矿业集团双阳煤矿矿井通风设计

I摘要双鸭山矿业集团双阳煤矿井田开采中所遇到的瓦斯、火、水、矿尘、冒顶等灾害。如何将这些不安全状态转变成为安全状态，这就需要在开采前、开采中采取一系列的灾害安全防治措施。针对瓦斯灾害，在开采初期通过矿井通风将开采过程中所释放出来的瓦斯稀释，后通过瓦斯抽放来降低工作面瓦斯的含量；针对煤层有自然发火倾向性，本设计通过向采空区注入液氮来防止采空区煤层自燃；针对煤矿可能发生的粉尘事故，设计采用湿式除尘、煤尘注水、个体防护等安全措施；针对矿井可能发生的水灾，设计采用接力排水的方法排出矿井积水；对于其他可能危害到矿井安全生产的隐患进行具体安全措施设计。最后，还设计给双阳矿建立一套KJ80安全监测系统来实时监控井下生产安全。关键词灾害通风爆炸监测IIAbstractShuangyashanMiningGroupagainstShuangyangcoalmineexploitationfacedbythegas、fire、water、mineraldust、cave-insandotherdisasters.Howwillthesechangesbecomeunsafestatesecuritystate，whichrequirestheminingago，Miningdisasterstakeaseriesofsecuritymeasuresforpreventionandtreatment.Forgasdisaster,Intheearlyminingthroughmineventilationminingprocesswillbereleasedbythegasdilution，AfterbackminedrainagegasneededtoreducetheFaceofgascontent；coalspontaneouscombustionaretendentiousThedesignthroughtothegoafinjectliquidnitrogentopreventthegoafcoalspontaneouscombustion；thedustaccident,designspecificallyforthecoalminemayhappenspecificallyforthecoalminemayhappenadoptsafepracticesuchaswetdyadicdustremoval,coaldustwaterinjection,individualprotection;thefloodspecificallyfortheshaftmayhappen,thepondingdesigningthatthemethodadoptrelaytodrainawaywaterdischargesashaft;Designthattomayendangertheconcretesafepracticebeinginprogresstothehiddentroublethatminesafetyproducesother.itisalsodesignedtoestablishasetofShuangyangKJ80MineSafetyMonitoringSystemtomonitorreal-timedownholeproductionsafety.KeywordsdisasterventilationexplosionmonitoringIAbstract........................................................II第1章矿井概况及安全条件........................................11.1井田概况············································································11.1.1地理概况····································································11.1.2气象及地震史······························································11.1.3自然灾害····································································21.1.4矿区经济概况······························································21.1.5电源及水源·································································21.2地质条件············································································21.2.1地质特征····································································21.2.2地质构造····································································31.2.3煤层及煤质·································································31.2.4矿井其它情况······························································41.2.5水文地质····································································41.3矿井生产(设计)概况······························································51.3.1工程性质····································································51.3.2井田开拓开采······························································51.3.3提升排水和压缩空气设备···············································51.3.4矿井主要运输设备························································61.3.5地面生产系统······························································61.3.6防洪··········································································61.3.7供电及通讯·································································71.3.8给水排水采暖通风及供热···············································71.3.9技术经济····································································8第2章矿井通风..................................................92.1概况··················································································92.2矿井通风············································································92.2.1通风方式和通风系统·····················································92.2.2安全逃生途径·····························································112.2.3矿井风量计算·····························································112.2.4通风设备及反风·························································13II第3章粉尘灾害防治.............................................153.1概述················································································153.2防尘措施··········································································153.2.1防尘措施··································································163.2.2工作面除尘·······························································173.2.3煤层注水防尘····························································173.2.4井下消防洒水系统······················································193.3防爆措施··········································································203.3.1防爆措施··································································203.3.2防止井下电气设备引燃煤尘爆炸措施······························203.3.3撒布岩粉··································································213.4隔爆措施··········································································223.4.1隔爆措施··································································223.4.2隔爆水棚··································································223.5矿井地面生产系统防尘·······················································243.5.1地面矿井尘源····························································243.5.2防尘措施及装备··············································
