本文介绍了几种系统岩体中存在裂隙时的矿山作业情况。这项研究的目的是确定岩石周围的岩体稳定性。提出了一种确定存在裂纹时岩石强度参数的方法。所进行的研究可以编制合理的数据表，以支持在各种采矿和地质条件下的矿山工作。采用统计方法处理数学建模结果，可以大大方便地计算作用在支架上的最大载荷，而无需在规定的岩石强度参数范围内直接建模。通过这种方式，可以在采矿公司中使用这种方法，而无需为数学建模准备复杂的初始数据。
The article describes the aspects of mine workings when there are cracks in the rock massif of several systems. The research is intended to determine the massif stability around rocks. A methodology to determine strength parameters of rocks in the presence of cracks was proposed. The undertaken studies allowed developing reasonable data sheets for supporting mine workings in various mining and geological conditions. Processing of mathematical modeling results by using statistical methods allows significantly facilitating the calculation of maximum load acting on the support without resorting to direct modeling within the specified range of rock strength parameters. In this manner, it becomes possible to use this approach in a mining company without complex preparation of initial data to accompany the mathematic modeling.
