综采工作面陷落柱超前静态预裂技术

Advance Static State Presplitting Technology of Collapse Colume in Fully Mechanized Mining Face

针对屯兰矿陷落柱特性,依据陷落柱的物理力学性质,合理设计静态破碎方案,对施工作业组织、设备配置、施工质量控制等重要环节进行综合分析,探讨高产高效矿井采取超前预裂静态破碎技术的应用可行性,为综采工作面稳产高产创造有利的条件,为今后其它矿井安全快速通过陷落柱提供新的思路。

In connection with property of collapse column in Tunlan coal mine, according to physical mechanics properties of collapse column, reasonably designs the scheme of static state fragmentation, carries out comprehensive analysing to important links of construction operations organizations, equipment configuration, construction quality control and so on, discusses the application feasibility of adopting advance presplitting static state fragmentation technology in mine of high yield and high efficiency creates favorable conditions for high and stable yield in fully mechanized mining face, provides new ideas for passing collapse column safely and rapidly in the other mines in future.
