摘要
结合黄陵矿业有限公司一号煤矿1#煤层赋存特点和地质概况,设计和优化了四号风井三条井筒过1#煤层的方案,实现了井筒穿过1#煤层时的安全、高效施工。并介绍了施工工艺,通过实践证实了此工艺的可行性。
Combined with the coal seam occurrence features and geology of No. 1Coal Mine in Huangling Mining Group Co.,Ltd,the sheme of 4#air shaft wellbore passing through 1#coal seam was designed and optimized,which realized the safe and efficient construction when the wellbore passed through 1#coal seam. The paper also introduced the construction technology and validated its feasibility in practice.
