| 摘 要： | 针对回采巷道支护系统中存在大量的随机性，本文采用改进的蒙特卡罗方法，根据锚杆支护回采巷道煤帮稳定的两个极限状态方程，对回采巷道煤帮锚杆支护可靠度计算进行了建模。与原始模型相比大大减少了计算量，克服了其中的不足，使计算结果更加科学。为锚杆支护参数设计提供可靠依据。

| Abstract: | In view of the randomness exists in the supporting system of the mining roadway. According to two steady limit state equations of the mining gateway wall that is supported by the bolt., the author adopts improvd Monte Carlo method to set up calculation model of the suopporting reliability to the mining gateway. Comparing with original model ,it greatly reduces the calculating amount, overcomes the existing insufficients ,makes the result of calculation more scientific, and provides the r.eliable evidence for the design of bolt supporting parameter. |
