摘要
文章以谢桥矿13216工作面所处的特殊地质条件为背景,在分析了注浆加固陷落柱作用机理的基础上,详细介绍了煤巷过陷落柱地质异常带影响区的注浆加固技术,并展开应用研究。现场工程实践表明,采用底板深孔注浆加固技术,能有效保证巷道的长期稳定,满足矿井的正常生产,对类似条件的煤巷支护具有重要的借鉴意义。
Taking the special geological conditions of No. 13216 coal mining face in Xieqiao Mine as the background, base on the analysis on the effect mechanism of the sink hole grouting reinforcement, the paper in detail introduced the grouting reinforcement technology for seam gateway driving through the geological abnormal zone of the sink hole and the applied study was conducted. The site engineering practices showed that the deep borehole grouting reinforcement technology of the floor applied could effectively ensure a long term stability of the gateway, could meet the normal production of the mine and would have the important references to the gateway support under the similar condition.
