| 摘 要： | 采空区对城市建设的影响越来越大,而公路下采空区治理多采用注浆方法,因此无论从质量、费用还是工期考虑,注浆配合比的合理选择都至关重要。结合重庆市万南高速公路下采空区注浆治理工程,较为系统地研究煤矿采空区治理注浆材料之间的相互关系,得出适用于该工程的合理浆液配合比,并为类似工程积累经验,对煤矿采空区的治理具有一定参考意义。

| Abstract: | The gob exhibits more and more influences on urban construction,while the grouting method is more adopted for treatment of gob under highway,therefore,reasonable choice of the mix ratio of grout is critical for quality,costs and period of construction.In combination with grouting treatment project for the gob below Chongqing Wansheng-Nanchuan Expressway,this paper systematically studies the interrelation between treatment of gobs in coal mines and grouting materials,and obtains the rational mix ratio of grout applicable to this project,and meanwhile accumulates experiences for similar project,showing a certain reference significance for treatment of gobs in coal mines. |
