摘　　要：依据冀西北寒冷地区张家口丰富的原料资源,对煤矿加固中的C-S浆材进行配方及性能研究,通过对注浆材料的固结强度与固结形貌的分析研究,来探索钠水玻璃波美度对煤矿加固中C-S浆材固结强度的影响规律。研究结果表明,当水玻璃浆液的波美度变大时,煤矿加固中的C-S浆材除了早期抗折强度变化波动较大之外,早期抗压强度、后期抗折及抗压强度均展现出稳中有升的态势,C-S浆材固结性能的发展趋势较为理想。Based on the rich raw material resources of Zhangjiakou in the cold region of northwestern Hebei, the formulation and properties of C-S slurry in coal mine reinforcement were studied. By analyzing and studying the consolidation strength and consolidation morphology of grouting material,the influence law of sodium silicate Baume degree on consolidation strength of C-S grouting material. The results show that,when the Baume degree increases,the early compressive strength,later flexural strength and later compressive strength of the C-S slurry is in a trend of steady,only the early flexural strength fluctuates greatly,and the C-S slurry consolidation performance of the development trend is ideal.
