A new method is proposed for predicting rock pressure with regard to statics, kinematics and dynamics. The static approach calculates strain state using the known classical method based on the mining guidelines. The kinematic approach takes into account the weight of overlying strata and makes the kinematic approach more specific. Dynamics is traced as nonlinear deformation in the course of mining, and the dynamic approach needs additional in-situ information on the rock mass behavior. The three approaches provide the total displacement of roof rocks in a production heading. The authors discuss a quasi-static approach determining dynamics in terms of the pliability of rocks ahead of an advancing face and feasibility of obtaining experimental data for the new method implementation.

开采过程中采掘巷顶岩石位移动力学

提出了一种从静力学、运动学和动力学角度预测岩石压力的新方法。静态方法使用基于挖掘指南的已知经典方法计算应变状态。运动学方法考虑了上覆地层的权重,使运动学方法更加具体。动力学被追踪为采矿过程中的非线性变形,而动力学方法需要额外的关于岩体行为的现场信息。这三种方法提供了生产掘进中顶板岩石的总位移。作者讨论了一种准静态方法,根据前进工作面前岩石的柔韧性以及获取新方法实施实验数据的可行性来确定动力学。
