Some theorems of compactly supported non-tensor product form two-dimension Daubechies wavelet were analysed carefully. Compactly supported non-tensor product form two-dimension wavelet was constructed, then non-tensor product form two dimension wavelet finite element was used to solve the deflection problem of elastic thin plate. The error order was researched. A numerical example was given at last.

Based on the elastic thin plate theory,the main law of the ore roof failure was analyzed and the formula of the ore roof thickness was *** results show that the tensile stress in the roof center accounts for the roof *** to the limit failure conditions of the point,the formula of the ore roof thickness was *** No.10 stope of a bauxite mine as an engineering case,the optimal thickness of the ore roof was 0.36 *** safety factor was taken as 1.3,therefore the design thickness was 0.5 *** the whole industrial test process,the dynamic alarm devices did not start the alarm and the ore roof was not *** with other stopes under similar conditions,its thickness was reduced by 0.1-0.3 *** recovery rate of the ore roof was increased by 16.7%-37.5%.
