摘要
长期以来煤矿回采工作面支护设计利用安全系数方法表示支护的安全性 ,强调加强支护密度替代支护质量 ,造成工作面生产成本高和效益低。论文利用结构可靠性方法研究了回采工作面支护可靠性设计 ,为提高煤矿工作面支护质量及安全。
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.
