摘要
针对高河矿井综放工作面陷落柱地质条件,在前期坑透探测及提前注浆分析陷落柱突水性基础上,采用局部打眼爆破配合采煤机截割方式强行通过陷落柱,保证了工作面的连续推进,为该矿井通过陷落柱提供了数据指导。
According to the geological condition of collapse columns of a fully-mechanized mining face in Gaohe Mine, on the basis of the preliminary tunnel perspective exploration and analysis on water inrush by pre-grouting, regional drilling blasting along with shearer cutting realized forced-passing the collapse columns, which ensured the continuous driving of the working face and provided the guidance with data for the working face passing the collapse columns.
