竹林山3＃煤层矿井瓦斯涌出量预测摘要：瓦斯是成煤过程中的伴生气体，它源于煤层又储存于煤层之中，一旦开采煤炭就会伴随有瓦斯涌出。瓦斯是一种灾害气体，它不但污染环境，而且可以诱发多种形式的灾害事故，对煤矿安全生产具有极大的危害性；同时，瓦斯又是一种高效洁净的能源，合理的开发与利用瓦斯可以让瓦斯造福于人类。矿井瓦斯涌出量预测的任务是确定新矿井、新水平、新采区、新工作面投产前瓦斯涌出量的大小，为矿井、采区和工作面提供瓦斯涌出方面的基础数据，它是矿井通风设计、瓦斯抽放和瓦斯管理的必不可少的基础参数。为了防止瓦斯突出，减少因为瓦斯突出而造成的人员伤亡和经济损失，本文在分析研究了几种瓦斯涌出量预测方法的基础上，选用分源预测法对矿井瓦斯涌出量进行预测。应用分源预测法预测矿井瓦斯涌出量，是以煤层瓦斯含量、煤层开采技术条件为基础，根据各基本瓦斯涌出源的瓦斯涌出规律，计算回采工作面、掘进工作面、采区以及矿井瓦斯的涌出量。本文采用的是竹林山煤矿中预测所需的原始资料，对煤矿瓦斯涌出量进行了精确的预测研究。关键词：煤层瓦斯含量涌出量预测分源预测法Thepredictionofgasemissionof3#coalbedinZhulinshanAbstract:Gasisassociatedwhencarboappeared.Itresultsfromcoalseamaswellasstoresinthecoalseam.Oncemineditwillbeaccompaniedbygasflowing.Gasisdamagedaero.Itisnotonlypollutedenvironmentbutalsocausetohappenpolymorphousdamagedisasterfailure.Itplaysanmuchhazardnesspartincoalminesafetyproduction.Meantime,gasisalsocleansource.rationalexploitationandusegasmaybringbenefittomanThedutyofpredictingthegasemissionairmakescertainnewmine,newlevel、newminingdistrict、gasemissionbeforenewworkplaceputintoproduction.Itsupplydatabaseforpit,miningdistrictandworkplace.Itisindispensablefoundationparameteraboutmineventilationdesign,gasdraingeandgasmanagement.Inordertopreventgasburst,reducedeadandwoundedandeconomiclosethatisbecausegasburst,thistextadoptedpredictedmethodnameddividethesourceandpredictthelaw,whichpredictgasemission.Andthetextusedsortsofpredictionmethod.Thatusepredictedmethodnameddividethesourceandpredictthelawforecasthowmuchpitairflowedusedcoalseammethanecontent、coalseamproductiontechnicalconditionasfundament，usedbasicgasflowrule，countedproductiveworkings、headingface、workingdistrictandpitair'sGasemission.ThistextusedbasicdatathatisforecastedfromZhulinshancoal.Itstudyedcoal-minegasemissionprecisely.Keywords：ThecontentofcoalseamGasemissiondividethesourceandpredictthelaw目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc137639929"1引言PAGEREF_Toc137639929\h1HYPERLINK\l"_Toc137639930"1.1国外研究现状PAGEREF_Toc137639930\h1HYPERLINK\l"_Toc137639931"1.2国内研究现状PAG
