The viewpoint about how to ensure safety production is expatiated from the aspect of safety management. Several questions that should be solved in mine safety management are discussed particularly firstly in this paper. In second part, with the principle of accident tree, some representative cases in one mine are analyzed, and more thirty laws are educed about the time, places and working procedure that easily make accidents happen, and the conclusion is confirmed by a lot of accident cases happened in our country. In third part, the Five Elements about mine safety are analyzed, they are: the basis is quality standardization, furnishment should be mechanised, management should be strictly based on laws, prevention should be ahead of time, the emphasis is group construction.

The nonlinear dynamic equations including the initial geometric imperfections of laminated composite cylindrical shells were derived from Hamilton's philosophy. Assuming the transverse displacements to be composed of axially symmetrical part and axially asymmetrical part, the governing equations expressed as displacement forms of dynamic buckling were obtained by Galerkin method. The equations were solved by finite difference method. The effects of impact velocity, lamination angle, initial geometric imperfection on the axial dynamic buckling of laminated composite cylindrical shells were discussed.

Firstly, the research studies the coding rule of the PDF417 barcode and designs related computer code algorithm, with making it programmed, and completes the coding part of the system software. Next, the coding and decoding principle of Reed-Solomon error-correcting code is briefly introduced. According to thecoding and decoding principle in galois field GF(929), to analyze and study its practical application with emphasis in this topic. Then, the PDF417 barcode decoding process is analyzed and studied detailed according to the barcode coding principle, with the corresponding realization method designed, improving the design in theory aspect by using material example, at the same time programming the design method to complete the decoding part of the system. Finally, validated the system program in the practical application of image information aspect, by using the nonrepeatability and the randomicity characteristic of Julia mark shape artwork.
