摘要
深部回采地压大,岩温高,为了安全回采必需采用胶结充填法。研究先用数值分析法验证湘西金矿深部开采采用胶结充填的必要性,然后以炉渣作基料研究一种新型胶凝剂,替代水泥,降低充填成本,利用新技术改造原有的充填系统,保证充填能够顺利进行。
The gluing packing technologies must be adopted for safety in deep extraction because temperature of rock and earth stress are higher,the necessities were verified in numerial analysis in xiangxi gold mine,it could lower the cost that slag used as basement and substituted cement in new adhesive,the new material and technologies were used to modifid the former packing system,It made the packing work freely.
