摘要
针对煤岩稳定性计算中存在的多种不确定因素影响计算结果准确度等问题,应用未确知信息理论,对煤层围岩力学参数进行未确知有理化,求解煤层围岩的未确知期望值,并对煤层围岩的稳定性进行分析和计算,结果表明:运用求解未确知期望的方法,来解决受不确定因素影响的地下工程中的未确知问题,较传统方法更精确、更简洁、更有效。未确知期望法在处理地下工程中的大系统优化问题时,值得进一步探讨和应用。
Aiming at the problem which all kinds of factors affected the accuracy of the calculation result existing in the stability calculation of the coal rock. Using the method of unascertained information theory, the authors did unascertained rationalization of coal seam wall rock mechanical parameter, computed unascertained expectation of coal seam wall rock, and analyzed and computed coal seam wall rock stability. The results show that the method of computing unascertained expectation is more effective, more compact and accurate than classic method in solving unascertained problems of substructure work which affected by the unascertained elements. It is worth to be discussed and applied further in solving the problem of optimizing large system in substructure work.
