Abstract

The features of mining of a coal series are described. The stress–strain behavior of rock mass during mining of the lower strata in the series is assessed with regard to the influence of coal pillars and upper level roadways. Different variants of location of a temporary roadway on the lower stratum in a series protected by a pillar are discussed. The implemented prediction of the stress–strain behavior of rock mass is adapted to the conditions of mines in the south of Kuzbass. This prediction is used to select the geomechanically safest variant of location of the temporary roadway.

岩体在开采系列下部地层过程中的应力-应变行为数值建模

摘要描述了煤系开采的特点。根据煤柱和上层巷道的影响，评估了该煤系下部地层开采过程中岩体的应力应变行为。讨论了在有煤柱保护的煤系下部地层上设置临时巷道的不同方案。根据库兹巴斯南部矿井的条件，对岩体的应力应变行为进行了预测。该预测用于选择地质力学上最安全的临时巷道位置。
