钻爆作业：采用钻孔台架配YTP-28手持式风动凿岩机钻孔，人工装药起爆。钻爆作业按照爆破设计进行钻眼、装药、接线和引爆。如围岩出现变化需要变更爆破设计时，由主管工程师确定。炮孔的装药、堵塞和引爆线路的连接，均由考核合格的爆炮工负责。①测量测量是控制开挖轮廓精确度的关键。采用隧道断面激光测量仪进行断面和炮孔划线。每循环都由测量技术人员在掌子面标出开挖轮廓和炮孔位置。②定位开眼采用钻孔台车钻眼时，台车与隧道走线保持平行，台车就位后按炮眼布置图正确钻孔。对于掏槽眼和周边眼的钻眼精度要求比其它眼要高，开眼误差要控制在3～5cm以内。③钻孔钻工要熟悉炮眼布置图，要能熟练地操纵凿岩机械，特别是钻周边眼，一定要丰富经验。钻孔时严格按照炮孔布置图正确对孔，以确保爆破质量。周边孔外插角1°～2°，炮孔相互平行，周边孔在断面轮廓线上开孔（在V、IV级围岩地段，周边孔在断面轮廓线内5～10cm处开孔），周边孔对孔误差环向不大于5cm。掏槽孔对孔误差不大于3cm，其它炮孔开眼误差不大于10cm。在钻眼过程中，应根据岩孔位置及掌子面岩石的凹凸程度调整炮眼程度，以保证炮眼底在同一平面上。④装药钻完孔后，用高压风吹孔，经检查合格后装药。装药分片分组负责，自上而下严格按爆破设计规定的装药量、雷管段号“对号入座”。爆破网路连接、检查及起爆，按照爆破设计要求和GB6722-86《爆破安全规程》执行。⑤堵塞所有装药的炮眼均堵塞炮泥，堵塞长度不小于40cm。⑥瞎炮处理发现瞎炮，应首先查明原因，如果是孔外的导爆管损坏引起的瞎炮，则切去损坏部分重新连接导爆管即可，但此时的接头应尽量靠近炮眼，如因孔内导爆管损坏或其第10页共12页feelfreetolistentotheirvoicesandhelpthemassessolveproblems,wewereofficiallyopenedonMay10"12345"Mayorcalls,formulatedrulesandregulations,equippedwithafull-timestaff,a24-houron-dutysystem,peopletocalltoreceive,reply,action,reminders,feedbackandsoon.Byyearend,handledthecrowdcalls1076,94.7%feedbackrate.　　ByMayorcallsactivecoordinationtosolvealargenumberofbearsontheimmediateinterestsofthepeopleandissuesofgreatlives,butalsoforleadershipresearchanddecisiontocollectalotofgoodideasandsuggestions,byallsectorsofthecommunityalike.Second,startMunicipalGovernmentAffairsHallbuilt.OnMay11,webuiltandlaunchedthecity-governmentlobby,weresettledin12departments,strictimplementationoffirstaskingdutysystem,servicesystem,systemofgratuitous,"receiving,internalcoordination,headofthewindowhandle,limitedtimeconcluded"one-stopservice.Bytheendoftodaytoacceptvarioustypesof3,273,originallyofupto100%.　　RunningGovernmentAffairsHall,theconvenienceofthemasses,promotingopenGovernment,improvetheinvestmentenvironmentandsolvetheirpracticalproblems,andsodidalotofwork,masses,servethecommunityfortheGovernmenttoplayaverygood"window,link,model".Third,createacitygovernmentpublicaffairsnetwork.WerelyontheGovernmentWebsite,wascompletedonMay24,theprovince"sfirstpublicaffairsnetwork.Over
