摘要
１９９７年，邢台矿在全煤（沿底托顶煤）巷道采用锚杆加锚索的支护技术获得成功。通过矿压观测分析对围岩在掘进和回采期的活动规律作了详细研究，为锚杆支护技术的推广提供了科学依据。
In 1997, the Xingtai Mine succeeded in using bolting & boltmesh supporting tech. in coal roadway(supporting the top coal along the bottom). By analyzing and observing the strata pressure, studies have been finished on the action law in coal - drilling and mining, which is the scientific evidence of the spreading of supporting tech.
