There are challenges of using composite laminates in the marine engineering, i.e., composites are frequently suffering from the effects of impaction including wave impaction, ship or other objects hitting, missiles or bullets hitting and other especially conditions.
Recently, fiber reinforced composite materials are widely used in marine engineering fields, such as hull panels, superstructure, propellers and fishing tools, etc.
However, using marine composites in the marine engineering also has challenges, i.e., they are frequently suffering from the effects of impaction including wave impaction in normal and extreme conditions, ship or other objects hitting, missiles or bullets hitting and other especial conditions [1].

"short, flat, long, subtraction, stay, support", put forward from the view of system engineering.
Many researches and engineering practice show that pressure relief could be fully worked by slits around 4-6m of coal seams.
The engineering practice shows that this method can make the gas drainage rate increases greatly
With the view of system engineering, taking synergistic method can get twice the result with half the effort.
