【Abstract】 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.更多还原
