基于可拓工程的方法，利用物元模型理论，对影响矿岩稳定性的多种因素进行综合评价，得出一种适合工程应用的评价方法。同时，对利用可拓学对事物进行评价作了简单介绍，具有一定的适用性。 Based on the method of extension engineering and using the matter element model theory, a comprehensive evaluation is made on a variety of factors that affect the stability of ore rock, and a suitable evaluation method for engineering application is obtained. At the same time, it gives a brief introduction to the use of extenics to evaluate things, which has some applicability.
