The authors study the process of the induced stress field formation in mining with the conventional and nature-like geotechnical systems, including frame and honeycomb mine structures. The rate of change in the natural stress field during mining is estimated using a new index—coefficient of influence. Based on the data of experimental mine research, as well as physical and numerical models, with regard to the numerical model calibration, the diagram of influence exerted on the rate of change in the natural stress field by the geometry of stopes in underground ore mining with the conventional and naturelike geotechnologies is plotted. It is found that the highest effect on the size of the induced tensile strain zones is exerted by the mining systems with caving of ore and enclosing rocks. The optimum coefficient of influence is a characteristic of the frame mine structure.

采矿几何形状对常规和类自然技术地下矿石开采中自然应力场的影响

作者研究了使用常规和类自然岩土工程系统（包括框架和蜂窝矿结构）在采矿中形成诱导应力场的过程。采矿过程中自然应力场的变化率是使用新的指标——影响系数来估计的。根据矿山试验研究数据，结合物理模型和数值模型，对数值模型标定，绘制了地下采场几何形状对自然应力场变化率的影响图。绘制了传统和自然的岩土技术。发现对诱导拉伸应变区的尺寸影响最大的是具有崩落矿石和围岩的采矿系统。
