高河矿井综放工作面过陷落柱技术

摘要

针对高河矿井综放工作面陷落柱地质条件，在前期勘探及钻探分析其突水性基础上，综合考虑了开采难度及煤层储量实际，采用“刀把”型工作面方式绕陷落柱方式开采，保证了工作面的连续推进和原煤的最大限度开采，为该矿井通过大陷落柱提供了数据指导。%Based on the geological condition of Gaohe fully mechanized caving face and the analysis of water -bursting at the early stage of exploration and drilling,this paper takes into consideration the recovery difficulty and the actual coal reserve,and mines the coalface with bypass the collapse column,so as to ensure the coalface continuity and the maximum mining,and which has provided lots of useful data for future coal mining influenced by the collapse column.
