摘　　要：对赵固一矿冲积层埋藏特点进行了分析,采用理论与实践相结合的分析方法,对设计基本参数进行优化,并按强度条件和变形条件设计了冻结壁厚度、安全掘进段高度、冻结孔布置方式和深度.实践表明,该优化设计方案能较好地满足现场工程实践的要求.The burying characteristic of alluvium in Zhaogu No. 1 Coal Mine is analyzed in this paper. The designing basic parameters are optimized on the basis of the combination of theory and experience. The frozen wall' s thickness, safety tunneling height, layout way of freezing holes and their depth are designed according to the strength and deformation. The experience indicated that this design could better cater for the demand of engineering practice.
