摘要
陷落柱是影响煤矿生产的地质因素之一,以塔山矿8210工作面为例,对回采过程中遇到的超大陷落柱提出了相应的技术措施,安全顺利快速的通过了陷落柱,为今后石炭二叠系煤层通过大型陷落柱积累了经验。
The collapse column is one of the geological factors affecting coal production. Based on the Tashan Mine 8210 face, for example, technical measures are put forward in confronting large collapse columns in the process of extraction to have safely and quickly passed the collapse column. This has accumulated valuable experience for the carboniferous Permian coal seam to pass large collapse column.
