摘要
通过对81401工作面仰孔分段注水法详细的井下观测,获得较准确的注水流量数据,通过数据分析,确定了试验区覆岩变形破坏范围,为高抽巷合理布置提供了理论依据。
By underground observation in drilling with upward-hole separated injection, the author determines the failure extent of overlying strata deformation in experimental are according to the obtained accurate water injection flow data, which can provide theoretical basis for reasonable layout of high-level suction roadway
