摘要 陷落柱是煤矿在采掘过程中常见的地质构造之一,会导致巷道支护工艺变更、巷道围岩变形量大、掘进效率降低、回采顶板维护困难等问题。此外,导水陷落柱可能引发突水事故。叙述了陷落柱形态及分布规律,分析了采掘工作面过陷落柱及控制顶板的主要措施,探讨了过陷落柱水灾事故的管控措施。 Collapse column is one of the common geological structures in coal mining process,which will lead to problems such as changes in roadway supporting technology,large deformation of roadway surrounding rock,reduce excavation efficiency and difficulty in roof maintenance of mining.In addition,the water-guiding collapse column may cause water inrush accidents.This paper described the shape and distribution law of the collapse column,analyzed main measures of the mining face passing through the collapse column and the management and control of the roof and discussed the control measures for preventing flooding accidents caused by collapse column.
