基于复杂地质条件下盲竖井掘进施工技术的探究

Exploration of Driving Construction Technology for Vertical Blind Shaft under Complex Geological Conditions

在复杂地质条件下,由于对于盲竖井地质条件掌握不清,掘砌施工技术难度大,施工工期长,给地下矿山基建工作造成影响大。该基建矿山盲竖井通过反井钻机施工数据分析,初步对盲竖井进行了破碎带分布推断,根据盲竖井的地质情况,有针对性的制定了提升、爆破技术参数和有效技术措施,掘进施工过程中顺利通过岩石破碎地段。

Under complex geological conditions,unclear understanding of the geological conditions of vertical blind shafts,difficult driving and masonry construction techniques,and long construction period have significant impacts on the infrastructure construction of underground mines.The vertical blind shaft of the infrastructure mine is analyzed through the construction data of raise-boring machine,and the distribution of the fractured zone of the vertical blind shaft is preliminarily inferred.Based on the geological conditions of the vertical blind shaft,targeted lifting and blasting technical parameters and effective technical measures are formulated,and the rock fracture zone is successfully passed through during the driving construction.
