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, Xingtai Coal Mine successfully applied the bolting and anchoring technology in the coal roadway along the top coal (along the roof and top coal). Through the observation and analysis of rock pressure, the law of surrounding rock movement during excavation and recovery is studied in detail, which provides a scientific basis for the promotion of bolt support technology.
