寺河矿特殊地质区域注浆加固技术研究

摘要

以寺河矿大采高工作面回采过程中遇到的特殊地质区域为背景,介绍了煤岩体注浆加固机理.分析了水泥浆液注浆技术和化学浆液注浆技术的应用情况,并对比分析了两种注浆材料的优缺点.实践证明,围岩注浆加固技术能有效改善特殊地质区域的煤岩体强度,对特殊地质区域的顶板管理起到良好效果,确保了工作面的安全生产.%Large mining height working face of Sihe mine encountered areas of special geological in minmg as the background, grouting reinforcement mechanism of coal and rock was intruduced. The application of cement slurry and chemical grouting technology were analyzed, the advantages and disadvantages of two grouting materials were analyzed too. The practice proves that grouting reinforcement technology of surrounding rock can effectively improved the special geological area of the coal and rock strength, the safety of working face ensured too.
