江西煤炭科技2023年第1期摘要:以二号回风立井项目井筒的建设为例,在对该井筒围岩力学条件分析的基础上,提出了凿岩爆破参数设计的原则及理论计算依据;结合实际生产初步设计包括掏槽眼、辅助眼和周边眼共计98个,填装炸药量总计488.75kg的爆破方案,并对爆破效果进行初步评估;然后,根据爆破效果总结初步设计爆破参数的不足,提出采用深度为5.3m、圈径为1.6m和2.0m的二阶掏槽眼以及深度为5.4m,圈径为6.6m的周边眼,配套辅助眼总计99个,填装447.5kg炸药的方案掘进。实践表明:优化后的凿岩爆破参数在一个循环内的掘进进尺增加至5.04m,炮眼利用率显著提升到95%。关键词:立井建设;光面爆破;掏槽爆破;掘进进尺中图分类号:TD262.1+1;TD23文献标识码:B文章编号:1006-2572(2023)01-0071-03ApplicationPracticeofDrillingandBlastingTechnologyinVerticalShaftConstructionWangPengxiang(MineConstructionBranchofXishanCoalPowerConstructionEngineeringGroupCo.,Ltd.,Taiyuan,Shanxi030000)Abstract:TakingtheshaftconstructionofNo.2returnairshaftprojectasanexample,basedontheanalysisofthemechanicalconditionsofthesurroundingrockoftheshaft,thepaperputsforwardthedesignprinciplesofdrillingandblastingparametersandthetheoreticalcalculationbasis,thenpreliminarilydesignsablastingschemeincluding98cutholes,auxiliaryholesandperipheralholes,and488.75kgofexplosivecharge,finally,basedontheblastingeffect,thepaperproposesatunnelingplanwithatotalof99secondarycutholeswithadepthof5.3m,acirclediameterof1.6mand2.0m,andaperipheralholewithadepthof5.4m,acirclediameterof6.6mandsupportingauxiliaryholes,filledwith447.5kgexplosives,whosepracticeshowsthatthedrivingfootageoftheoptimizeddrillingandblastingparametersinacycleisincreasedto5.04m,andtheutilizationrateoftheblastholeissignificantlyincreasedto95%.Keywords:verticalshaftconstruction;smoothblasting;cutblasting;drivingfootage凿岩爆破技术在立井施工中的应用实践王鹏翔(西山煤电建筑工程集团有限公司矿建分公司,山西太原030000)根据西山煤电的统一规划,西铭矿二号回风立井项目井筒的深度为1071.0m,井筒的有效直径6.0m,有效面积为28.26m2,立井的掘进直径为6.6m。该项目的立井井口的标高为+871m,井底的标高为-200m。初步设计该...
