综放工作面动压巷道小煤柱支护技术研究

Research on small coal pillar support technology of dynamic pressure roadway in fully mechanized caving face

面对采空侧动压巷道支护困难的难题,提出了留设窄煤柱、高强度锚索支护的设计方案,通过施工论证和矿压监测分析,证明优化后的支护技术满足了巷道支护强度的要求,适合推广使用。

Aiming at the roadway support difficult problems closing the gob, proposed retaining narrow coal pillar, high strength anchor support design, through the use in site and mine pressure monitoring analysis proves that the optimization support technology meet the requirements of roadway support strength, which is suitable for promotion.
