摘要
平煤股份十三矿明斜井冲积层段有34m长位于机械厂房下方。在穿越该段施工中,根据工程特点,采用井下工作面管棚预注浆与地面厂房预注浆加固相结合的施工方案,并采用短段掘砌施工方法,正规循环作业,安全顺利地完成了施工任务,同时保证了斜井上方机械厂房的正常生产。
The alluvium section of the mine inclined shaft in No.13 Mine of Pingdingshan Coal Company Limited had a length of 34 munderneath of a machinery workshop building.The construction of the section passing through the building,according to the engineering features,a construction plan combined with the tube shield pre-grouting at the underground working face and the pre-grouting reinforcement of the surface ground workshop building was applied.A short sectional heading and lining construction method was applied with a normal circulated operation.The construction mission was safely and successfully completed and the normal production in the workshop above the mine inclined shaft was ensured.
