摘要
以作业面破碎顶板治理防护为对象开展探究,结合具体工程实际,在分析破碎顶板注浆加固机理的基础上,对注浆加固工艺开展全面分析总结,并对其实际应用效果做出检测分析。结果表明,通过注浆加固,顶板强度和完整性显著提升,回采作业安全大幅提高,对矿井生产产生积极意义。
This paper explored the control and protection of broken roof in working face.Combined with the specific engineering practice,on the basis of analyzing the grouting reinforcement mechanism of broken roof,it comprehensively analyzed and summarized the grouting reinforcement technology,and made detection and Analysis on its practical application effect.The results show that through grouting reinforcement,the strength and integrity of roof are significantly improved,and the safety of mining operation is greatly improved,which has a positive significance for mine production.
