摘要
针对义马煤田开采深部冲击地压巷道所遇到的底鼓问题及防治难点,提出底板切槽卸压技术,在耿村煤矿13210掘进工作面运输巷进行了防治底鼓的现场应用。结果表明,底板切槽卸压技术应用效果良好,为防治冲击地压巷道底鼓问题提供了科学依据。
Aiming at the problems of floor heave and its control in deep roadway with rock burst danger of Yima coal field, floor grooving pressure relief technology was proposed in this paper,and floor heave control methods was put into practice on 13210 driving face of scientific basis to the prevention of roadway floor heave, and has good promotion prospects.
