| Abstract: | The mines have been utilizing method of safe coefficient to show security of coal face supporting design at all times and emphasizing strengthening density of supporting prop to assure production safety, it is higher in production cost and lower in efficiency. The paper utilizes theory way of structure reliability to make a study of design method of supporting reliability in coal face and it is suggested that mines raiese supporting quality and safety and bating production cost in coal face. |
